15.5 square yards = 140 square feet.
1 sq yard = 9 sq feet so 6400 sq yards = 6400*9 = 57600 sq feet.
depends on the depth that you need to cover the 1200 square feet (area) to. there are 3 foot to 1 yard (1 foot=3 yards). so 1 square foot = 9 square yards (3x3). 1200 square feet = 1200 x9 = 10,800 square yards. you then multiply the 10,800 by the amount of yards (depth) that you want to cover the area to.
Assuming the yards means square yards, there are 33 sq yd * 9 sq ft/sq yard = 297 sq feet.
9 sq feet = 1 sq yard so 15*20 = 300 sq ft = 33.33... sq yards
There are 9 square feet in 1 square yard. Therefore, 1200 square feet is equal to 133.33 square yards (1200 divided by 9).
133.3 sq yards
1200 sq metres = 12916.69 sq feet
One square yard = 3ftX3ft so 3x3= 9 square feet per square yard, divide 1200 square feet by 9 = 133.333 square yards.
1200 sq meters = ~12,916.7 sq feet.
1200 sq metres = 12916.7 sq feet
9 SQ feet = 1 SQ yard. 840 SQ feet = 931/3 SQ yards
129 sq. feet = 14.33 sq. yards
700 sq feet = 77.8 sq yards.
2178 sqare feet = 726 square yards * * * * * NO! 9 sq ft = 1 sq yard so 2178 sq feet = 2178/9 sq yards = 242 sq yards.
900 * 1200 = 1080000 sq feet
1 sq yard = 9 sq feet so 200 sq yards = 9*200 = 1800 sq feet.
