Carpet costs $15 per square yard. if a room is 12 feet by 21 feet, how much will it cost to carpet the room? a) $3780b) $420! : 3

$420

Step-by-step 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
