Question:

A house contains one 12-foot-x-14-foot bedroom, one 12-foot-x-10-foot bedroom, and one 8-foot-x-12-foot bedroom. What’s the total amount of carpeting needed to carpet all three bedrooms?

A 128 square yards
Explaination

Find the area of each bedroom and add them together: 12 × 14 = 168; 12 × 10 = 120;
8 × 12 = 96. 168 + 120 + 96 = 384 square feet. Then, because 3 feet make up a yard, divide the total area in square feet by 3 to determine the number of square yards needed: 384 ÷ 3 = 128 square yards.
