If 60% of a rectangular floor is covered by a rectangular rug of 9 feet by 12 feet, what is the area in square feet of the floor?

A 65
B 108
C 180
D 270

Correct Answer: 180

Area of rectangular RUG = (base)(height) = (9)(12) = 108 This RUG covers 60% of the FLOOR In other words, 108 = 60% of the area of the FLOOR Or we can write: 108 = 0.6(area of FLOOR) So, 108 /0.6 = area of FLOOR Evaluate to get: 180 = area of FLOOR
