Hekp A living room floor measures 11 feet by 18.9 feet as indicated by the solid outline in the diagram below. The owner estimated the floor to be 12 feet by 20 feet as indicated by the dashed outline.

Flooring for the room costs $8 per square foot. What is the approximate difference in cost between the flooring to cover the actual area and the flooring to cover the estimated area of the living room floor?


A) $150


B) $320


C) $50


D) $250


E) $40

Answer 1

Answer: The actual area of the living room floor is 11 feet * 18.9 feet = 208.9 square feet. The estimated area of the living room floor is 12 feet * 20 feet = 240 square feet.

The difference in cost between the flooring to cover the actual area and the flooring to cover the estimated area of the living room floor is 240 square feet - 208.9 square feet = 31.1 square feet.

Therefore, the approximate difference in cost is 31.1 square feet * $8 per square foot = $248.80, which is closest to option (D) $250.
