The ratio between the perimeter and the width of a rectangle is 5:1. If the area of the rectangle is 384 square centimeters, what is the length of the rectangle in centimeters? Choose the correct choice from the following answers:
A) 20	B) 21	C) 22	D) 23	E) 24
Perimeter = 2(W+L) = 5W   3W = 2L   W = 2L/3   WL = 384   2L^2/3 = 384   L^2 = 576   L = 24 cm   The answer is 24.
