Question

What will it cost to carpet a rectangular floor measuring 21 feet by 24 feet if the carpet costs $ 31.96 per square​ yard?

Answer 1

Area of a rectangle is equal to the base multiplied by the height. However, you are given the measurements in feet, and these must be divided by 3 to get yards.

21 becomes 7, and 24 becomes 8. 7/8 = 56 yards squared.

Multiplied by $31.96, the total comes out to $1789.76.
