The answer is 336 sq ft or 37.33 sq yd (37 1/3 square yards).
3.11 square yards = 28 square feet.
252 square feet = 252/9 square yards = 28 square yards
12' x 21' (252 square feet) = 28 sq. yards.
Multiply the two dimensions to get the area. In this case the calculation gives you 252 square feet. Divide by 9 to get square yards, so that is 28.
Alright, darling, let's get this straight. First, we convert those pesky feet to meters because apparently, we can't just stick to one unit of measurement. 21ft is roughly 6.4m and 12ft is about 3.7m. Now, we multiply 6.4 by 3.7 to get a square meterage of around 23.68 square meters. Voila!
3.11 square yards = 28 square feet.
Total square yards: 87.11
252 square feet = 28 square yards.
252 square feet = 252/9 square yards = 28 square yards
28 * 18 / 9 = 56 square yards.
24.444 (recurring) square yards.
28' x 14' (392 square feet) = 43.5 square yards of carpet needed.
28 square feet = 3.1 square yards of material.
