Question

the perimeter of the rectangle is 130 meters. If the longest side is one less than twice the shortest side, what is the length of each side

Answer 1

L=43 and W=22

Explanation:

The perimeter of a rectangle is 130 meters. We also know the longest side called the length is 1 less than twice the width or 2w-1. The width is w. To find perimeter, you must use the formula P=2l+2w.

130 = 2(2w-1) +2w

130 = 4w -2 +2w

130 = 6w -2

132 = 6w

132/6 = w

22 = w

So the length is l=2w-1=2(22)-1 = 43
