Question:

A patio measures 12 feet by 14 feet. How many 8-inch-square paving stones are needed to pave the patio?

A
252

Explaination

First multiply length × width to determine the area of the patio: 12 feet × 14 feet = 168 square feet. Next determine the area in square inches that needs to be covered: 168 square feet × 12 inches = 2,016 square inches. Finally, divide that answer by the size of the stones to determine the number of stones needed: 2,016 ÷ 8 = 252.
