Asked by Renee :)

Sally wants to build a fence around her pool. The pool is 26 feet long and 21 feet wide. The fence is to be 15 feet from the edge of the pool.

What are the dimensions of the area surrounding the pool?

How many feet of fencing will Sally need?

A. 41 ft by 36 ft; 77 ft**
B. 41 ft by 36 ft; 154 ft
C. 56 ft by 51 ft; 214 ft
D. 56 ft by 51 ft; 107 ft

I am not sure on this, can you tell me if I am right, and how to do it?
Answered by Ms. Sue
Your answer is wrong.

Perimeter = (2 * L) + (2 * W)

L = 26 + 30
W = 21 + 30

Ok is it D?
Answered by Ms. Sue
No;. 107 feet is only half way around. That won't do to have only half the pool fenced.

You've tried two guesses. Now you're on your own. Please do not post this question again.
Answered by Renee :)
I wasn't guessing
I added 26 and 30 to get 56
then i added 21 and 30 to get 51
then I added them together to get 107
so, is it d?
