If a room is 10 feet by 21 feet then its area = 10 * 21 = 210 square feet. There are 3 feet in a yard. There are therefore 3 * 3 = 9 square feet in a square yard. Thus to convert we now divide by 9.
Therefore this is 210/9 = 23 1/3 square yards.
Alternatively, and if you prefer, you can convert your measurements first. As there are 3 feet to a yard then 10 feet = 10/3 = 3 1/3 yards. 21 feet = 21/3 = 7 yards.
3 1/3 * 7 = 23 1/3 square yards.
