Question 896772: The length of a rectangle is three times its width.
If the perimeter of the rectangle is
80yd
, find its area. Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! P = 80 (given)
L = 3W (given)
P = 2L + 2W
80 = 2L + 2W
80 = 2(3W) + 2W
80 = 6W + 2W
80 = 8W
10 = W
If the width is 10, then the length is 3x that, or 30.
