12' x 21' (252 square feet) = 28 sq. yards.
214 x 7 sq feet in 1500 sq feet with a remainder of 2 sq feet.
12 square mtrs
= 24 x 36 sq feet = 864 sq feet
1 acre is 4840 sq yards. Now 1 sq yard = 9 sq feet (3 feet x 3 feet), so 1 acre = 43560 sq feet. your area is 170 x 70 sq feet = 11900 sq feet. So this is 11900/43560 of an acre, answer = 0.273 acre.
1 foot = 1.03937 meters 144sf x 1.03937(1meter) = 149.67 sq feet
1600
1 foot = 12 inches Answer = (21/12) x (21/12) = 49/16 sq feet = 3.0625 sq feet
12 feet X 21 feet / 9 sq feet/sq yard = 28 sq yards
12' x 21' (252 square feet) = 28 sq. yards.
336 sq feet
32*21 = 672 sq inches = 672/(12)2 = 42/3 sq feet
Answer = 21 ft x 13 ft = 273 sq feet
11' * 11' = 121 sq ft = 11.241 sq metres (to 3 dp)
Assuming you mean 11 feet by 17 feet, a sq yard is 3 x 3 = 9 sq feet 11 x 17/9 = 20.8 sq yards required, or about 21 sq yards
length x width = sq ft
214 x 7 sq feet in 1500 sq feet with a remainder of 2 sq feet.
