A rectangular pool has a length 2m shorter than twice its width.

a.) write an expression to determine the pool's perimeter. What is it's perimeter?

b.) write an expression to determine the surface area of the pool. What is the surface area?

Answered by Ms. Sue
P = 2L + 2W
P = 2(2W - 2) + 2W
P = 6W - 4

A = LW
A = (2W-2) * W

Answered by Rihanna
