If the perimeter of a certain rectangle is 76 m and its area is 360 m2 , then what is the length of its shortest side ?

A 13
B 15
C 18
D 10

Correct Answer: 18

Perimeter . = 2(l + b) = 76 i.e. l + b = 38 Area = l*b = 360 :et's think of two numbers whose sum is 38 and whose products is 360 (Instead of making a quadratic equation and creating more difficulty for ourselves) The numbers are 18 and 20 Smaller side = 18
