a rectangle is 5 feet longer than it is wide. the perimeter of the rectangle is 34 feet. what is the length of the rectangle?
2 answers:
P = 2(L + W)...perimeter of a rectangle formula P = 34 L = W + 5 34 = 2(W + 5 + W) 34 = 2(2W + 5) 34 = 4W + 10 34 - 10 = 4W 24 = 4W 24/4 = W 6 = W.....width is 6 ft L = W + 5 L = 6 + 5 L = 11 <=== length is 11 ft
The length is 11 feet and the width is 7 feet long
