Lou is roping a boundary for an event at a local carnival. She has 144 feet of rope, and the event supervisor has instructed her to rope an area that is three times as long as it is wide. Find the length of each roped side
-----
Let each side be "x.
Then each length is "3x".
---
Perimeter = 2(width + length)
144 = 2(x + 3x)
77 = 4x
x = 77/4 ft = 19 1/4 ft (width)
---
3x = 3(77/4) = (3/4)77 = 57 3/4 ft (length)
