The perimeter of a rectangular swimming pool is 160 feet. The length of the swimming pool is four times its width. Find the dimensions of the swimming pool.

Formula for Perimeter of Rectangle:

P = 2 (L + W)

Plug in 160:

160 = 2 (L + W)

L = 4W

So we can plug in '4W' for 'L' in the first equation.

160 = 2 (L + W)

160 = 2 (4W + W)

Combine like terms:

160 = 2 (5W)

160 = 10W

Divide 10 to both sides:

W = 16

Now we can plug this back into any of the two equations to find the length.

L = 4W

L = 4 (16)

L = 64

So the width is 16, and the length is 64.

Width = 16

length=64

This is the correct answer
