Question 628427: Please help me solve this problem.
The perimeter of a rectangle is found by using the formula: 2L + 2W. if the perimeter of a rectangle is 66 cm, and the length is twice the width, what is the length? Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! The perimeter of a rectangle is found by using the formula: 2L + 2W.
if the perimeter of a rectangle is 66 cm, and the length is twice the width
what is the length?
2L + 2W = 66:
"the length is twice the width"; therefore
L = 2W
replace L with 2W
2(2W) + 2W = 66
4W + 2W = 66
6W = 66
W = 66/6
W = 11 cm
therefore
2(11) = 22 cm is the length
