Question

Bob and Carol want to hire Able Refinishing to sand and refinish the dining room floor to match the floor in the living room. Able charges $2.89 per square foot to sand and refinish a hardwood floor. The dining room is rectangular and measures 17 feet 8 inches by 11 feet 8 inches. Find the area of the dining room floor, rounded up to the next square foot, and the cost of the work.

Answer 1

206.1 ft^2 rounded up to 207 ft^2

$595.66 rounded to $598.23

[The problem says to round UP]

Explanation:

Let's convert the dining room measurements into feet.

17' 8" = 17 + 8/12 feet

= 17.67 feet

11' 8" = 11 + 8/12 feet

= 11.67 feet

Area = (17.67 feet)*(11.67 feet) = 206.1 ft^2

Area rounded up is 207 ft^2

At $2.89/ft^2, the total cost would be:

($2.89/ft^2)*(206.1 ft^2) = $595.66, or

($2.89/ft^2)*(207 ft^2) = $598.23 if the area is rounded up.
