L feet
W
= L – 8 feet
Suppose that you need to fence a rectangular play area in your backyard for your child or pet. Further, suppose that you know the length must be 8 feet longer than the width. The back of your house will serve as one side of the fenced area.
Note: The perimeter (distance around) of a general rectangle is P = 2L + 2W, and its area is A = L x W. In this situation, P = L + 2W.
1. Based on the first letter of your last name, choose a value for your backyard area that must be fenced from the range corresponding to the first letter of your last name indicated in the following table.
