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 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.
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.
189 square feet. (multiply square yards by 3 to get square feet)
Total square yards: 16.0
126 square yards.
