Finding the length and width of a 96m pool.

[I jus dunno]

A swimming pool has a perimeter of 96m. The length is 3m more than twice the width. Find the length and width of the pool.

We think it is 2l(+3) + 2w =96 but we can't get the correct answer.

Help, please

Let

Width of the pool = W

Length of the pool = L = 2*W + 3 ......................(1)

then perimeter P = 2*L + 2*W = 96

Then

2*(2*W + 3) + 2*W = 96

Solve for W then solve for L using (1)

Thank you so much!

okay,
2*(2W+3) + 2(W) = 96
4W+6 +2W =96
6W +6 = 96
6W = 90
W = 15


2*W +3
2(15) +3
30 +3 = 33 = L
