Question

A rectangular athletic field is twice as long as it is wide. If the perimeter of the athletic field is 360 yards, what are its dimensions?

Answer 1

The width is 60 and the length is 120

Explanation:

Let l = length

Let w = width

l = 2w

Perimeter

l + l + w + w = 360 Substitute 2w for l

2w + 2w + w + w =360 Combine line terms

6w = 360 Divide both sides by 6

w = 60

If w = 60 then l = 120
