I will answer this by first converting the measurements to yards, but you could also calculate the area in feet and then convert to square yards when finished (as I will also show). There is no right or wrong way to do it.
12 feet = 12/3 = 4 yards
21 feet = 21/3 = 7 yards
Thus the area of the room = 4 * 7 = 28 square yards.
The other way to calculate this is to work in feet initially, thus 12 * 21 = 252 square feet. 1 square yard = 3 * 3 = 9 square feet. Thus the area = 252/9 = 28 square yards.

How may square yards in 30x25 foot room?
30*25=750 square feet To convert this to yards, divide by 3. 750/3=250 square yards
12 foot x 50 foot x 6 inch how may yards of concrete?
12*50/6=100 100 square yards
How may square feet in a 10 foot x 12 foot room?
120ft^2 , 10ft * 12ft
How may yards are there in 70 square feet?
A yard is a unit of length. A square foot is a unit of area. The two units are therefore incompatible.
How do you figure yards of carpet?
L x W / 9 = sq yards Multiply the length times the width and divide by 9 to get the square yards. Just remember, the amount you have to buy may be more depending on the size of your room and the sizes of the rolls of carpet available.
