### Example Question #1 : How To Find The Area Of A Parallelogram

Find the area of the given parallelogram:

**Possible Answers:**

**Correct answer:**

Find the area of the given parallelogram:

To find the area of a parallelogram, simply do the following:

Where b is the base, and h is the height. Note that the height is the length of the perpendicular line connecting both bases. In this case, our height is 12mi and our base is 144 miles.

### Example Question #1 : How To Find The Area Of A Parallelogram

Find the area of the given parallelogram:

**Possible Answers:**

**Correct answer:**

Find the area of the given parallelogram:

To find the area of a parallelogram, simply use the following formula for area of a parallelogram:

Where b is the base, and h is the height. Note that the height is the length of the perpendicular line connecting both bases. In this case, our height is 12 mi and our base is 144 mi.

### Example Question #1 : How To Find The Area Of A Rectangle

What is the total surface area of the enclosed region?

**Possible Answers:**

112cm^{2}

212cm^{2}

168cm^{2}

114cm^{2}

126cm^{2}

**Correct answer:**

114cm^{2}

First, we must find the missing lengths. Because we know that the length going horizontally across on the bottom is 6 cm and 8 cm, that must mean that the length going across at the top must also equal this sum.

So, the length of the top must equal

6 + 8 =

14.

We are given one value of the length on the top, 4. To find the missing horizontal length on the top, we must subtract 4 from 14.

14 – 4 = 10.

In order to find the other missing length, we must observe that the greatest vertical length of this figure is 12 cm. Because we are given 4 cm and 5 cm, we must subtract 4 and 5 from 12 to find the other missing length.

12 – 4 – 5 =

3.

Now, let's divide this enclosed region in three separate rectangles.

The rectangle at the top has a length of 4 cm and width of 3 cm.

The middle rectangle has a length of

10 + 4 =

14 cm

and a width of 5 cm.

The bottom rectangle has a length of 8 cm and width of 4 cm.

If the formula for the area of a rectangle is length x width, we must now calculate the individual areas of each rectangle and add them up.

Area of top rectangle

4 x 3 = 12cm^{2}

Area of middle rectangle

14 x 5 = 70cm^{2}

Area of bottom rectangle

8 x 4 = 32cm^{2}

12cm^{2} + 32cm^{2} + 70cm^{2 }=

114cm^{2}

### Example Question #2 : How To Find The Area Of A Rectangle

Mr. Barker is building a rectangular fence. His yard has an area of 24 feet, and the one side of the fence he's already built is 6 feet long.

What is the length of the other side (the width) of the fence?

**Possible Answers:**

**Correct answer:**

The answer is 4 feet, because

and a rectangle must have 4 sides, with 2 sides of one length and 2 sides of another.

feet

making the other side 4 feet,

### Example Question #1 : How To Find The Area Of A Rectangle

If Bailey is making a quilt for a bed that measures feet wide and feet long, and she wants there to be an extra foot of quilt to hang over each side of the bed, how much material should she buy.

**Possible Answers:**

**Correct answer:**

In order to determine how much material Bailey needs, we must first find the area of space she needs to cover. Since Bailey would like the quilt to be an extra foot on each side, we must add feet to both the length and width.

Width

Length

Now we apply the formula for the area of a rectangle, which is .

### Example Question #1 : How To Find The Area Of A Rectangle

Give the area of the rectangle in the above diagram.

**Possible Answers:**

**Correct answer:**

Multiply the length by the width to get the area of the rectangle:

The area of the rectangle is 198 square inches.

### Example Question #5 : How To Find The Area Of A Rectangle

Which could be the dimensions of a rectangle with the area ?

**Possible Answers:**

**Correct answer:**

To find the area, simply multiply the sides of the rectangle. The only sides which add up to are:

### Example Question #1 : How To Find The Area Of A Rectangle

Give the area of the above rectangle in square centimeters.

**Possible Answers:**

**Correct answer:**

Since 1 meter = 100 centimeters, multiply each dimension by 100 to convert meters to centimeters. This makes the dimensions 200 centimeters by 500 centimeters.

Use the area formula, substituting :

### Example Question #1 : Rectangles

Mr. Smith is planting a rectangular garden with a length of 5 ft and a width of 7 ft. What is the area of the garden?

**Possible Answers:**

**Correct answer:**

The area of a rectangle can be calculated by multiplying the length by the width.

### Example Question #1 : How To Find The Area Of A Rectangle

Sally's room measures 100 square feet. Which type of measurement is this?

**Possible Answers:**

Area

Perimeter

Volume

Width

Length

**Correct answer:**

Area

Area is measured in units squared, and volume is measured in units cubed. Width, length, and perimeter are all measured in regular units.

Therefore, 100 square feet is the area of the room.
