Question 901284: 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.The area is 8265. What is the area and the preimeter in terms of the lenght?
Answer by josgarithmetic(39630) (Show Source): You can put this solution on YOUR website!
L=w+8, and for enclosing the play area, p=2w+L, and you know a constant area A to be A=wL.

w=L-8 from given information.
.

When you know or given a value for area A, you can find L and use L to find p.
