Question 1008809: the length of a rectangle is 7 cm more than four times the width. if the perimeter is 44 cm. what are the length and width of the rectangle? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Perimeter P = 2L + 2W = 44 or
L + W = 22
Then we also have
L = 7 + 4W
Substitute that into the first equation and we get
7 + 4W + W = 22
5W + 7 = 22
5W = 15
W = 3 cm
L = 22-3 = 19 cm
