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 carpet needed to carpet all three bedrooms, given that one carpet = 1 yard?

Detailed Explanation
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 9 square feet make up a square yard, divide the total area in square feet by 9 to determine the number of square yards needed:
384 ÷ 9 = \(42\tfrac{2}{3}\) square yards.
12 × 14 = 168;
12 × 10 = 120;
8 × 12 = 96. 168 + 120 + 96 = 384 square feet.
Then, because 9 square feet make up a square yard, divide the total area in square feet by 9 to determine the number of square yards needed:
384 ÷ 9 = \(42\tfrac{2}{3}\) square yards.
