Step-by-step explanation:

LET X = length of the pool

then

x+3 = WIDTH of the pool

Remember, the perimeter of any rectangle is:

W + W + L + L

2W + 2L

2(W + L)

So, rewriting the above with our variable we have:

96 = 2(x + x+3)

96 = 2(2x+3)

96 = 4x+6

90 = 4x

22.5 METERS = x (length of pool)

width:

x+3 = 22.5+3 = 25.5 meters (width of pool)
