A. 65
B. 108
C. 180
D. 270

View Answer	Favorite Question

Answer: Option B

Explanation:

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
