Question

Mason, a hardwood flooring installer, needs to calculate the amount of hardwood flooring needed to cover a floor that’s 3 3/4 yards Wide and 5 1/2 yards Long. How many square yards of hardwood flooring are needed? (Area= Length x Width). A) 20 5/8 B)15 3/8 C)18 3/4 D)16 1/2

Answer 1

A floor that is 3 3/4 yards wide and 5 1/2 yards long requires 20 5/8 square yards of hardwood flooring area.

length = 5 1/2 yd, breadth = 3 3/4 yd.

Make fractions out of both measurements first.

3 3/4 = 3 + 3/4

= 12/4 + 3/4

= 15/4

5 1/2 = 5 + ½

= 10/2 + ½

= 11/2

Area = (15 * 11)/(4 * 2) yd2

Area = 165/8 yd2

They essentially believed that 165/8 = 20 leftover 5 area = 20 5/8 yd2.
