Question 1

Kevin has a rectangular piece of paper with area 56\frac{5}{6} square foot. He cuts it into strips that are each 14\frac{1}{4} foot wide. If the original paper was 53\frac{5}{3} feet long, how many strips did he make?

  1. 12÷14=2\frac{1}{2} ÷ \frac{1}{4} = 2 strips (correct answer)
  2. 56÷14=103\frac{5}{6} ÷ \frac{1}{4} = \frac{10}{3} strips
  3. 53÷14=203\frac{5}{3} ÷ \frac{1}{4} = \frac{20}{3} strips
  4. 12×14=18\frac{1}{2} × \frac{1}{4} = \frac{1}{8} strips
Explanation: When you see a problem about cutting paper into strips, you need to figure out what measurement determines how many strips you can make. The key is understanding which dimension matters for the cutting. Since Kevin cuts the paper into strips that are 14\frac{1}{4} foot wide, he's cutting across the width of the rectangle. To find how many strips he gets, you need to divide the width of the original paper by the width of each strip. First, find the original width using the area formula. Since Area = length × width, we have 56=53×width\frac{5}{6} = \frac{5}{3} \times \text{width}. Solving for width: width=56÷53=56×35=12\text{width} = \frac{5}{6} ÷ \frac{5}{3} = \frac{5}{6} \times \frac{3}{5} = \frac{1}{2} foot. Now divide the width by the strip width: 12÷14=12×41=2\frac{1}{2} ÷ \frac{1}{4} = \frac{1}{2} \times \frac{4}{1} = 2 strips. Choice A is correct. Choice B incorrectly divides the total area by the strip width, but area doesn't tell you how many strips you can cut. Choice C divides the length by the strip width, but since he's cutting across the width (not along the length), the length doesn't determine the number of strips. Choice D multiplies instead of dividing, which would give you a portion of a strip rather than counting strips. Remember: When cutting strips, always identify which dimension is being divided. If strips are a certain width, divide the paper's width by the strip width to find how many strips you get.

Question 2

Maria is tiling a rectangular garden bed with square tiles. Each tile has side length 14\frac{1}{4} foot. She uses 6 tiles along the length and 8 tiles along the width to completely cover the bed. What is the area of the garden bed?

  1. 144\frac{14}{4} square feet
  2. 4816\frac{48}{16} square feet (correct answer)
  3. 244\frac{24}{4} square feet
  4. 484\frac{48}{4} square feet
Explanation: First, find the dimensions: length = 6 × 14\frac{1}{4} = 64\frac{6}{4} feet, width = 8 × 14\frac{1}{4} = 84\frac{8}{4} feet. Area = 64×84=4816\frac{6}{4} × \frac{8}{4} = \frac{48}{16} square feet. Choice A adds the dimensions instead of multiplying. Choice C incorrectly calculates 6 × 4 in the numerator. Choice D uses the wrong denominator.

Question 3

A rectangle is 34\tfrac{3}{4} inch by 24\tfrac{2}{4} inch. You tile it with unit fraction squares that are 14\tfrac{1}{4} inch by 14\tfrac{1}{4} inch, so each tile has area 116\tfrac{1}{16} square inch. The tiles fill the rectangle exactly. What is the area of the rectangle? (Multiplying side lengths should match the number of tiles times 116\tfrac{1}{16}.)

  1. 54\tfrac{5}{4} square inch
  2. 38\tfrac{3}{8} square inch (correct answer)
  3. 516\tfrac{5}{16} square inch
  4. 64\tfrac{6}{4} square inch
Explanation: The core skill is finding the area of a rectangle with fractional side lengths by multiplying the length and width directly. We can tile the rectangle with unit fraction squares that are 1/4 inch by 1/4 inch, each covering 1/16 square inch, and here the 3/4-inch by 2/4-inch rectangle fits exactly 6 such tiles without gaps or overlaps. The total area from tiling, which is 6 times 1/16 or 3/8 square inch, connects directly to multiplying the side lengths 3/4 by 2/4 to get the same 3/8 square inch. The area is expressed in square inches, meaning the equivalent of 1-inch by 1-inch units, with small square tiles illustrating fractional divisions. A common misconception is that all tiles must be the same shape as the unit square, but any unit fraction tiles that fit work to verify the area. Visual models like this grid support the multiplication method for fractional areas. These models generalize to show how area formulas remain reliable for fractions, fostering deeper mathematical insight.

Question 4

A rectangle is 34\tfrac{3}{4} meter by 34\tfrac{3}{4} meter. You tile it with unit fraction squares that are 14\tfrac{1}{4} meter by 14\tfrac{1}{4} meter. The tiling makes 3 squares along each side. Which value is the correct area in square meters (and matches 34×34\tfrac{3}{4}\times\tfrac{3}{4})?

  1. 916\tfrac{9}{16} square meter (correct answer)
  2. 68\tfrac{6}{8} square meter
  3. 32\tfrac{3}{2} square meter
  4. 98\tfrac{9}{8} square meter
Explanation: The core skill involves determining the area of a rectangle with fractional sides, for example, one measuring 3/4 meter by 3/4 meter, by multiplying the side lengths. This is illustrated by tiling with unit fraction squares that are 1/4 meter by 1/4 meter, placing 3 along each side to form 9 small squares. The connection to multiplication is evident as 3/4 times 3/4 yields 9/16 square meter, matching the total area from the 9 squares each of 1/16 square meter. Square units like square meters represent the two-dimensional extent of the shape. A misconception might be that squares must have equal sides for area, but rectangles with fractional sides function similarly. Visual tiling models reinforce the area formula by showing fractional decomposition. Broadly, these models generalize the idea that multiplication applies universally to find areas, bridging concrete visuals to abstract formulas.

Question 5

A small garden bed is a rectangle that is 23\tfrac{2}{3} meter long and 12\tfrac{1}{2} meter wide. You tile it with unit fraction squares that are 13\tfrac{1}{3} meter by 12\tfrac{1}{2} meter. The tiling shows 2 squares along the length and 1 square along the width. Multiplying the side lengths should give the same area as the tiling. What is the area of the garden bed?

  1. 76\tfrac{7}{6} square meter
  2. 25\tfrac{2}{5} square meter
  3. 56\tfrac{5}{6} square meter
  4. 13\tfrac{1}{3} square meter (correct answer)
Explanation: The core skill is computing the area of rectangles with fractional side lengths, such as a garden bed 2/3 meter by 1/2 meter, via fraction multiplication. We demonstrate this through tiling with unit fraction squares of 1/3 meter by 1/2 meter, arranging 2 along the length and 1 along the width for 2 total squares. This tiling relates to multiplication because 2/3 times 1/2 equals 1/3 square meter, aligning with the 2 small squares each of area 1/6 square meter. Area is denoted in square units, like square meters, indicating the planar space occupied. A frequent misconception is that partial squares are needed for fractions, but unit fraction tiles fit exactly. Tiling models aid in understanding the area formula by visualizing fraction products. In essence, such models extend the concept to show that area formulas hold for fractions, promoting deeper mathematical insight.

Question 6

A rectangular baking pan is 12\tfrac{1}{2} foot by 34\tfrac{3}{4} foot. You partition it into unit fraction squares that are 12\tfrac{1}{2} foot by 14\tfrac{1}{4} foot. The partition shows 1 square along one side and 3 squares along the other side, for 1×31\times3 small squares. Which area matches both the tiling and 12×34\tfrac{1}{2}\times\tfrac{3}{4}?

  1. 54\tfrac{5}{4} square foot
  2. 38\tfrac{3}{8} square foot (correct answer)
  3. 74\tfrac{7}{4} square foot
  4. 58\tfrac{5}{8} square foot
Explanation: The core skill is finding areas of rectangles with fractional sides, like a baking pan 1/2 foot by 3/4 foot, by multiplying the fractions. This concept is explained by partitioning into unit fraction squares of 1/2 foot by 1/4 foot, with 1 along one side and 3 along the other, totaling 3 small squares. The link to multiplication is that 1/2 times 3/4 results in 3/8 square foot, corresponding to the 3 squares each covering 1/8 square foot. Square units, such as square feet, measure the two-dimensional coverage of the rectangle. One misconception is believing fractions complicate area without visuals, but tiling clarifies it. Models like tiling support the area formula by breaking down fractions into countable units. Generally, these approaches generalize how multiplication formulas work for any rational side lengths, strengthening geometric reasoning.

Question 7

A rectangle is 23\tfrac{2}{3} inch by 23\tfrac{2}{3} inch. You tile it with unit fraction squares that are 13\tfrac{1}{3} inch by 13\tfrac{1}{3} inch. The tiling shows 2 squares along each side. What is the area of the rectangle?

  1. 49\tfrac{4}{9} square inch (correct answer)
  2. 46\tfrac{4}{6} square inch
  3. 89\tfrac{8}{9} square inch
  4. 43\tfrac{4}{3} square inch
Explanation: The core skill is calculating rectangular areas with fractional sides, for instance, a 2/3 inch by 2/3 inch shape, using fraction multiplication. We tile it with unit fraction squares of 1/3 inch by 1/3 inch, fitting 2 along each side for 4 small squares. This connects to multiplication as 2/3 times 2/3 equals 4/9 square inch, matching the area from 4 squares each of 1/9 square inch. Square units like square inches quantify the surface area in two dimensions. A common misconception is that areas with fractions are approximate, but exact tiling shows precision. Tiling models illustrate the area formula through visual fraction representation. Overall, these models help generalize that area computation via multiplication is consistent across whole and fractional numbers.

Question 8

A rectangular photo is 23\tfrac{2}{3} inch by 23\tfrac{2}{3} inch. Imagine tiling it with unit fraction squares that are 13\tfrac{1}{3} inch by 13\tfrac{1}{3} inch. Counting the squares measures area in square inches, and multiplying the side lengths gives the same area as tiling. What is the area of the photo?

  1. 49\tfrac{4}{9} square inch (correct answer)
  2. 46\tfrac{4}{6} square inch
  3. 83\tfrac{8}{3} square inch
  4. 79\tfrac{7}{9} square inch
Explanation: The core skill is finding the area of a rectangle with fractional sides, such as a photo that is 2/3 inch long and 2/3 inch wide, by multiplying those lengths to get 4/9 square inch. Tiling the rectangle with unit fraction squares that are 1/3 inch by 1/3 inch helps visualize how the space is covered without gaps or overlaps. Counting the tiles shows there are 4 such squares, each with area 1/9 square inch, totaling 4/9 square inch, which connects directly to multiplying 2/3 by 2/3. The area is measured in square inches, where each square inch represents a 1 inch by 1 inch unit, but fractions allow for partial units. A common misconception is that areas with fractional sides must be whole numbers, but tiling demonstrates that fractional areas are valid and precise. Models like tiling build intuition for why the area formula works with fractions. These visual aids generalize to support the formula area equals length times width for any real numbers.

Question 9

A rectangular placemat is 34\tfrac{3}{4} foot long and 12\tfrac{1}{2} foot wide. You can tile it with unit fraction squares that are 14\tfrac{1}{4} foot by 12\tfrac{1}{2} foot to measure area in square feet. Multiplying the side lengths gives the same area as counting the tiles. What is the area of the placemat?

  1. 54\tfrac{5}{4} square foot
  2. 56\tfrac{5}{6} square foot
  3. 38\tfrac{3}{8} square foot (correct answer)
  4. 74\tfrac{7}{4} square foot
Explanation: The core skill is finding the area of a rectangle with fractional sides, such as a placemat that is 3/4 foot long and 1/2 foot wide, by multiplying those lengths to get 3/8 square foot. Tiling the rectangle with unit fraction squares that are 1/4 foot by 1/2 foot helps visualize how the space is covered without gaps or overlaps. Counting the tiles shows there are 3 such squares, each with area 1/8 square foot, totaling 3/8 square foot, which connects directly to multiplying 3/4 by 1/2. The area is measured in square feet, where each square foot represents a 1 foot by 1 foot unit, but fractions allow for partial units. A common misconception is that areas with fractional sides must be whole numbers, but tiling demonstrates that fractional areas are valid and precise. Models like tiling build intuition for why the area formula works with fractions. These visual aids generalize to support the formula area equals length times width for any real numbers.

Question 10

A craft paper rectangle is 34\tfrac{3}{4} inch long and 34\tfrac{3}{4} inch wide. You can tile it with unit fraction squares that are 14\tfrac{1}{4} inch by 14\tfrac{1}{4} inch to measure area in square inches. Multiplying the side lengths gives the same area as counting those tiles. What is the area of the paper rectangle?

  1. 98\tfrac{9}{8} square inch
  2. 32\tfrac{3}{2} square inch
  3. 916\tfrac{9}{16} square inch (correct answer)
  4. 34\tfrac{3}{4} square inch
Explanation: The core skill is finding the area of a rectangle with fractional sides, such as a craft paper that is 3/4 inch long and 3/4 inch wide, by multiplying those lengths to get 9/16 square inch. Tiling the rectangle with unit fraction squares that are 1/4 inch by 1/4 inch helps visualize how the space is covered without gaps or overlaps. Counting the tiles shows there are 9 such squares, each with area 1/16 square inch, totaling 9/16 square inch, which connects directly to multiplying 3/4 by 3/4. The area is measured in square inches, where each square inch represents a 1 inch by 1 inch unit, but fractions allow for partial units. A common misconception is that areas with fractional sides must be whole numbers, but tiling demonstrates that fractional areas are valid and precise. Models like tiling build intuition for why the area formula works with fractions. These visual aids generalize to support the formula area equals length times width for any real numbers.

Question 11

A rectangle is 34\tfrac{3}{4} yard by 34\tfrac{3}{4} yard. You tile it with unit fraction squares that are 14\tfrac{1}{4} yard by 14\tfrac{1}{4} yard, so each tile has area 116\tfrac{1}{16} square yard. The tiles exactly cover the rectangle. What is the area of the rectangle? (Multiplying 34×34\tfrac{3}{4}\times\tfrac{3}{4} should match the tiled area.)

  1. 64\tfrac{6}{4} square yard
  2. 68\tfrac{6}{8} square yard
  3. 916\tfrac{9}{16} square yard (correct answer)
  4. 716\tfrac{7}{16} square yard
Explanation: The core skill is finding the area of a rectangle with fractional side lengths by multiplying the length and width directly. We can tile the rectangle with unit fraction squares that are 1/4 yard by 1/4 yard, each covering 1/16 square yard, and here the 3/4-yard by 3/4-yard rectangle fits exactly 9 such tiles without gaps or overlaps. The total area from tiling, which is 9 times 1/16 or 9/16 square yard, connects directly to multiplying the side lengths 3/4 by 3/4 to get the same 9/16 square yard. The area is expressed in square yards, representing 1-yard by 1-yard units, with square tiles showing even subdivisions. A common misconception is that squaring a fraction is different from regular multiplication, but it's just multiplying the fraction by itself. Visual models like this grid tiling illustrate the area formula for squares and rectangles with fractions. These models generalize to uphold area calculations for all cases, strengthening geometric reasoning.

Question 12

A rectangle is 34\tfrac{3}{4} meter by 12\tfrac{1}{2} meter. It is tiled with unit fraction squares that are 14\tfrac{1}{4} meter by 12\tfrac{1}{2} meter, so each tile has area 18\tfrac{1}{8} square meter. The tiling fits exactly.

  2. 32\tfrac{3}{2} square meter
  3. 38\tfrac{3}{8} square meter (correct answer)
  4. 64\tfrac{6}{4} square meter
Explanation: The core skill is finding the area of a rectangle with fractional side lengths by multiplying the length and width directly. We can tile the rectangle with unit fraction squares that are 1/4 meter by 1/2 meter, each covering 1/8 square meter, and here the 3/4-meter by 1/2-meter rectangle fits exactly 3 such tiles without gaps or overlaps. The total area from tiling, which is 3 times 1/8 or 3/8 square meter, connects directly to multiplying the side lengths 3/4 by 1/2 to get the same 3/8 square meter. The area is expressed in square meters, representing the coverage equivalent to 1-meter by 1-meter units, with fractional tiles showing subdivided parts. A common misconception is that tiling only works with square tiles, but rectangular unit fraction tiles also cover exactly and confirm the area. Visual models like this tiling help explain the multiplication formula for fractional areas. These models generalize to support area calculations for any fractions, providing a foundation for advanced geometry concepts.

Question 13

A rectangle is 24\tfrac{2}{4} meter long and 23\tfrac{2}{3} meter wide. You tile it with unit fraction squares that are 14\tfrac{1}{4} meter by 13\tfrac{1}{3} meter, so each tile has area 112\tfrac{1}{12} square meter. The tiling has no gaps or overlaps. What is the area of the rectangle? (Tiling and multiplying 24×23\tfrac{2}{4}\times\tfrac{2}{3} should match.)

  1. 412\tfrac{4}{12} square meter (correct answer)
  2. 712\tfrac{7}{12} square meter
  3. 47\tfrac{4}{7} square meter
  4. 44\tfrac{4}{4} square meter
Explanation: The core skill is finding the area of a rectangle with fractional side lengths by multiplying the length and width directly. We can tile the rectangle with unit fraction squares that are 14\tfrac{1}{4} meter by 13\tfrac{1}{3} meter, each covering 112\tfrac{1}{12} square meter, and here the 24\tfrac{2}{4}-meter by 23\tfrac{2}{3}-meter rectangle fits exactly 4 such tiles without gaps or overlaps. The total area from tiling, which is 4 times 112\tfrac{1}{12} or 412\tfrac{4}{12} square meter, connects directly to multiplying the side lengths 24\tfrac{2}{4} by 23\tfrac{2}{3} to get the same 412\tfrac{4}{12} square meter. The area is expressed in square meters, equivalent to 1-meter by 1-meter units, using tiles to depict fractions. A common misconception is that different denominators prevent exact tiling, but choosing tiles matching the denominators ensures precision. Visual models like this support the multiplication approach for fractional areas. These models generalize to validate area formulas universally, enhancing learning outcomes in math.

Question 14

Use the diagram shown to answer the question. The shaded rectangle has been tiled with unit squares. What is the area of the shaded rectangle?

  1. 209\frac{20}{9} square centimeters (correct answer)
  2. 56\frac{5}{6} square centimeters
  3. 43\frac{4}{3} square centimeters
  4. 1518\frac{15}{18} square centimeters
Explanation: From the diagram, the rectangle has 5 unit squares along length and 4 unit squares along width, with each unit square having side length 13\frac{1}{3} cm. Rectangle dimensions: 53\frac{5}{3} cm by 43\frac{4}{3} cm. Area = 53×43=209\frac{5}{3} × \frac{4}{3} = \frac{20}{9} square cm. Choice B incorrectly adds dimensions. Choice C uses wrong calculation. Choice D represents an incorrect fraction computation.

Question 15

A rectangle is tiled with unit squares of side length 110\frac{1}{10} inch. There are 15 squares along the length and 8 squares along the width. Which expression correctly represents both the area calculation by counting squares and by multiplying side lengths?

  1. 15×8×110=32×4515 × 8 × \frac{1}{10} = \frac{3}{2} × \frac{4}{5}
  2. 120×110=1510+810120 × \frac{1}{10} = \frac{15}{10} + \frac{8}{10}
  3. 120×1100=1510×810120 × \frac{1}{100} = \frac{15}{10} × \frac{8}{10} (correct answer)
  4. 15×8×1100=15100×810015 × 8 × \frac{1}{100} = \frac{15}{100} × \frac{8}{100}
Explanation: When you see a rectangle tiled with unit squares, you need to connect two different ways of finding area: counting the squares directly and multiplying the rectangle's side lengths. Let's work through this step by step. You have 15 squares along the length and 8 squares along the width, so counting squares gives you 15×8=12015 × 8 = 120 total squares. Since each square has area 110×110=1100\frac{1}{10} × \frac{1}{10} = \frac{1}{100} square inches, the total area is 120×1100120 × \frac{1}{100} square inches. Now for the side lengths: the length is 15×110=151015 × \frac{1}{10} = \frac{15}{10} inches, and the width is 8×110=8108 × \frac{1}{10} = \frac{8}{10} inches. Multiplying these gives area = 1510×810\frac{15}{10} × \frac{8}{10} square inches. Choice C correctly shows both methods are equal: 120×1100=1510×810120 × \frac{1}{100} = \frac{15}{10} × \frac{8}{10}. Choice A uses 110\frac{1}{10} instead of 1100\frac{1}{100} for the unit square area, forgetting that area requires squaring the side length. Choice B tries to add the side lengths instead of multiplying them, and also uses the wrong unit square area. Choice D makes two errors: it uses 1100\frac{1}{100} in the counting method (should be 1100\frac{1}{100}) and incorrectly represents the side lengths as 15100\frac{15}{100} and 8100\frac{8}{100}. Remember: when unit squares have side length ss, their area is s2s^2, not just ss. Always square the side length when finding the area of each unit square.

Question 16

A rectangle is 23\tfrac{2}{3} yard by 34\tfrac{3}{4} yard. It is partitioned into unit fraction squares that are 13\tfrac{1}{3} yard by 14\tfrac{1}{4} yard, making 2 squares by 3 squares. Which statement is the incorrect claim about the area, based on measuring in square units?

  1. The area is 12\tfrac{1}{2} square yard because there are 6 unit fraction squares and each is 112\tfrac{1}{12} square yard.
  2. The area is 1712\tfrac{17}{12} square yard because 23+34=1712\tfrac{2}{3}+\tfrac{3}{4}=\tfrac{17}{12}. (correct answer)
  3. The area is 12\tfrac{1}{2} square yard because 23×34=612\tfrac{2}{3}\times\tfrac{3}{4}=\tfrac{6}{12}.
  4. Multiplying the side lengths gives the same area as counting the small squares in the partition.
Explanation: The core skill is finding rectangular areas with fractional sides, like 2/3 yard by 3/4 yard, via fraction multiplication. Partitioning into unit fraction squares of 1/3 yard by 1/4 yard creates a 2 by 3 grid of 6 small squares. The multiplication link is 2/3 times 3/4 equaling 1/2 square yard, matching 6 times 1/12 square yard. Square units, such as square yards, denote the area coverage. One misconception is adding fractions for area, like 2/3 + 3/4 = 17/12, which wrongly confuses it with linear addition. Such tiling models bolster the area formula by contrasting correct multiplication with errors. Overall, they generalize the support for formulas, showing how visuals prevent misconceptions in fractional geometry.

Question 17

A rectangular index card is 23\tfrac{2}{3} inch long and 14\tfrac{1}{4} inch wide. You can tile it with unit fraction squares that are 13\tfrac{1}{3} inch by 14\tfrac{1}{4} inch to measure area in square inches. Multiplying the side lengths gives the same area as tiling. What is the area of the index card?

  1. 1112\tfrac{11}{12} square inch
  2. 27\tfrac{2}{7} square inch
  3. 83\tfrac{8}{3} square inch
  4. 16\tfrac{1}{6} square inch (correct answer)
Explanation: The core skill is finding the area of a rectangle with fractional sides, such as an index card that is 2/3 inch long and 1/4 inch wide, by multiplying those lengths to get 1/6 square inch. Tiling the rectangle with unit fraction squares that are 1/3 inch by 1/4 inch helps visualize how the space is covered without gaps or overlaps. Counting the tiles shows there are 2 such squares, each with area 1/12 square inch, totaling 1/6 square inch, which connects directly to multiplying 2/3 by 1/4. The area is measured in square inches, where each square inch represents a 1 inch by 1 inch unit, but fractions allow for partial units. A common misconception is that areas with fractional sides must be whole numbers, but tiling demonstrates that fractional areas are valid and precise. Models like tiling build intuition for why the area formula works with fractions. These visual aids generalize to support the formula area equals length times width for any real numbers.

Question 18

A rectangular rug is 34\tfrac{3}{4} meter long and 23\tfrac{2}{3} meter wide. If you tile it using unit fraction squares that are 14\tfrac{1}{4} meter by 13\tfrac{1}{3} meter, you can count tiles to measure area in square meters. Multiplying the side lengths gives the same area as tiling. What is the area of the rug?

  1. 1712\tfrac{17}{12} square meter
  2. 67\tfrac{6}{7} square meter
  3. 512\tfrac{5}{12} square meter
  4. 12\tfrac{1}{2} square meter (correct answer)
Explanation: The core skill is finding the area of a rectangle with fractional sides, such as a rug that is 3/4 meter long and 2/3 meter wide, by multiplying those lengths to get 1/2 square meter. Tiling the rectangle with unit fraction squares that are 1/4 meter by 1/3 meter helps visualize how the space is covered without gaps or overlaps. Counting the tiles shows there are 6 such squares, each with area 1/12 square meter, totaling 1/2 square meter, which connects directly to multiplying 3/4 by 2/3. The area is measured in square meters, where each square meter represents a 1 meter by 1 meter unit, but fractions allow for partial units. A common misconception is that areas with fractional sides must be whole numbers, but tiling demonstrates that fractional areas are valid and precise. Models like tiling build intuition for why the area formula works with fractions. These visual aids generalize to support the formula area equals length times width for any real numbers.

Question 19

A rectangular science notebook cover is 12\tfrac{1}{2} foot by 23\tfrac{2}{3} foot. Imagine partitioning it into unit fraction squares that are 16\tfrac{1}{6} foot by 16\tfrac{1}{6} foot so the area is measured in square feet. Multiplying the side lengths gives the same area as counting the tiles. What is the area of the cover?

  1. 76\tfrac{7}{6} square foot
  2. 13\tfrac{1}{3} square foot (correct answer)
  3. 56\tfrac{5}{6} square foot
  4. 45\tfrac{4}{5} square foot
Explanation: The core skill is finding the area of a rectangle with fractional sides, such as a notebook cover that is 1/2 foot long and 2/3 foot wide, by multiplying those lengths to get 1/3 square foot. Tiling the rectangle with unit fraction squares that are 1/6 foot by 1/6 foot helps visualize how the space is covered without gaps or overlaps. Counting the tiles shows there are 12 such squares, each with area 1/36 square foot, totaling 1/3 square foot, which connects directly to multiplying 1/2 by 2/3. The area is measured in square feet, where each square foot represents a 1 foot by 1 foot unit, but fractions allow for partial units.

Question 20

A rectangular sandbox is 23\tfrac{2}{3} yard long and 12\tfrac{1}{2} yard wide. If you tile it with unit fraction squares that are 13\tfrac{1}{3} yard by 12\tfrac{1}{2} yard, you can count the tiles to measure area in square yards. Multiplying the side lengths gives the same area as tiling. What is the area of the sandbox?

  1. 45\tfrac{4}{5} square yard
  2. 76\tfrac{7}{6} square yard
  3. 56\tfrac{5}{6} square yard
  4. 13\tfrac{1}{3} square yard (correct answer)
Explanation: The core skill is finding the area of a rectangle with fractional sides, such as a sandbox that is 2/3 yard long and 1/2 yard wide, by multiplying those lengths to get 1/3 square yard.
