Example Question #84 : Quadrilaterals

If the length of a rectangle is 7.5 feet and the width is 2 feet, what is the value of  if the area is ?

Possible Answers:

Correct answer:

Explanation:

The area of a rectangle is calculated by multiplying the length by the width. Here, the length is 7.5 and the width is 2, so the area will be 15. 

Given that the area is also equal to , the value of  will be 3, given that 3 times 5 is 15. 

Example Question #85 : Quadrilaterals

If a cereal box has a volume of 40 cubic inches, a width of 2 inches, and a height of 5 inches, what is its length? 

Possible Answers:

Correct answer:

Explanation:

The formula for the volume of a rectangular solid is .

Use the provided information from the question in the above formula and solve for the length.

Therefore, the length of the box is 4 inches. In answering this question, it is important to look at the units before selecting an answer. It is easy to be tricked into thinking that because the total answer is in cubic inches that it may be necessary to have square inches, but when multiplying three values, each with inches as their units, the units of the product will be cubic inches.
