Question 1145625: The length of a rectangle is five times it’s width. If the perimeter of the rectangle is 84cm, find its area? Answer by ikleyn(52803) (Show Source):
L + W + L + W = 84, L = 5W ===========>
5W + W + 5W + W = 84
12W = 84
W = 84/12
W = 7 cm
L = 7*5 = 35 cm
The area of the rectangle = L*W = 35*7 = 245 cm^2. ANSWER
