The ratio between the perimeter and the width of a rectangle is 5 : 1. If the area of the rectangle is 294 sq. cm, what is the width of the rectangle?  Choose the correct choice from the following:
A) 10 cm
B) 12 cm
C) 14 cm
D) 16 cm
E) 18 cm
2L+2W = 5W   L = 3W/2   W*L = 294   3W^2/2 = 294   W^2 = 196   W = 14   The answer is 14 cm.
