Square feet measure area, and yards measure length. If you mean FEET in 21 yards, the answer is 63 (3 times 21). If you mean square feet in 21 SQUARE YARDS, the answer is 189 (three times three times 21).
18 feet is 6 yards, and 21 feet is 7 yards. 6 multiplied by 7 is 42. Therefore, it's 42 square yards.
(12-ft x 21-ft) / (9 square feet per square yard) = 28 square yards
7*5 = 35 square yards
12 feet X 21 feet / 9 sq feet/sq yard = 28 sq yards
21 feet by 21 feet is 441 square feet which converts to 49 square yards.
21 square yards = 189 square feet.

Total square yards: 16.0
126 square yards.
18 feet is 6 yards, and 21 feet is 7 yards. 6 multiplied by 7 is 42. Therefore, it's 42 square yards.
1 square foot is 0.111 square yards. The floor area is 9feet x 21feet = 189 square feet. Therefore, the total square yards is: 189 square feet x 0.111 square yards/foot squared = 21 square yards Therefore, there is 21 square yards of floor.
37.3 square yards.
12' x 21' (252 square feet) = 28 sq. yards.
Multiply the two dimensions to get the area. The calculation will give you 189 square feet, which converts to 21 square yards.
(21/3) x (6/3) = 14 square yards
