The length of a sand volleyball court is twice its width. The perimeter is 180 feet. Find the length and width of the sand volleyball court.

Since we know that length is twice the width, we can say that:

Perimiter = 2 (twice the width) + 2 (width)

Therefore, P = 2 (2w) + 2 (w)

this simplifies to P=6w

Sine P=180, 160 = 6w, so w = 30

Because length is twice the width, length = 2 * width, or 2*30, which is 60

Therefore:

length = 60

width = 30
