How many square yards of carpet are needed

[eddy2017]

How many square yards of carpet are needed to completely cover a rectangular floor that measures 15 feet by 9 feet?

I will find the area in feet and then take to yards
$$A= l * w$$$$A=15 (ft) * 9(ft)$$$$A=135 ft^2$$Now converting to yards
There are 3 ft to 1 yard
So
$$135 ÷ 3= 45 yd^2$$Is this correct?
Thanks

No. Areas are in square feet and square yards, not feet or yards, so the conversion is different. One square yard is 3 feet by 3 feet, making it 9 square feet, not 3.

Try converting to yards first and see what you get. That's a great way to learn these ideas well (and to check your answer).

15 ft to yards = 5 yards
9 ft to yards= 3 yards
Area in yards= 5 yd × 3 yd= 15 yd^2
15 square yards of carpet are needed
