Question

You want to carpet two rooms. One is 12 ft x 15 ft. The other is 28 ft x 20 ft. If carpet is $13.75 per square yard, what is the total cost to carpet the two rooms?

Answer 1

If you prefer, since those foot measurements don't convert to handy whole-yard measurements, you can think of a square yard as 3 feet x 3 feet, or 9 square feet.

 

So the carpet costs 13.75 per 9 square feet. Divide that to get the cost per ONE square foot, then calculate the square-foot areas of the two rooms and multiply your per-square-foot cost by that number.

 

Either way works great!

Answer 2

You will have to convert your measurements from feet to yards and then find the area of each rooms. Then multiply the cost ($13.75 per square yard) to each area. Finally, add the costs and you get your total cost.
