The length of a rectangular floor is one and a half times its breadth. What is the perimeter of the floor (in meters) if its area is 216 sq meters

A 40

B 50

C 60

D 44

Solution

Correct Answer: Option C

A/Q,

x*x*1.5 = 216

or, x2 = 216 / 1.5

or, x2 = 144

or, x = 12

breadth = 12

so, length is = 1.5 * 12 = 18

Thus, perimeter = 2 * (12 + 18)

= 2 * 30

= 60
