The lengths of the sides of a rectangle are in a ratio of 4:7. If the length is 31.5 in., find the width, perimeter and area of this rectangle.
Answered by Ms. Sue
4/7 - 31.5/W
4W = 220.5
W = 55.125

P = 2L + 2W

A = LW

Answered by unowen
4:7 as n:31.5
4/7=n/31.5
7n=126
n=18
P=2(18)+2(31.5)
A=18 x 31.5
