<PRE><B>Question 317512</B>
length = 5x

width = x

area = 125

A = L*W

125 = (5x)(x)

125 = 5x^2

125/5 = x^2

25 = x^2

sqrt{25} = sqrt{x^2}

5 = x

The width is 5 feet.

The length is 5 times 5 feet or 25 feet.

To find the perimeter, we use P = 2L + 2W.

P = 2(25) + 2(5)

P = 50 + 10

P = 60 feet.

Done!
