7 The dimension you provide is not a squared dimension but a linear dimension. There are no squared dimensions in a linear dimension. There are 7 linear yards in 21 linear feet, but no squared yards.
21 feet by 21 feet is 441 square feet which converts to 49 square yards.
21 square yards = 189 square feet.
189 square feet. (multiply square yards by 3 to get square feet)
Total square yards: 16.0
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).
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.
37.3 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.
28
12' x 21' (252 square feet) = 28 sq. yards.
(21/3) x (6/3) = 14 square yards
