Answer 1

$420

Explanation:

First convert the room measurements from feet to yards to match the unit of measure of the carpet.

Room size is 12 feet by 21 feet.

3 feet = 1 yard.

12/3 = 4 yards

21/3 = 7 yards

4 yards times 7 yards = 28 square yards

28 square yards times $15 per square yards = $420.
