273 square feet. Multiply length by width - the result is the area in square feet.
21 square feet
21*21 = 441 square feet.21*21 = 441 square feet.21*21 = 441 square feet.21*21 = 441 square feet.
The room is 226 square feet.
If a room is 10 feet by 21 feet then its area = 10 * 21 = 210 square feet. There are 3 feet in a yard. There are therefore 3 * 3 = 9 square feet in a square yard. Thus to convert we now divide by 9.Therefore this is 210/9 = 23 1/3 square yards.Alternatively, and if you prefer, you can convert your measurements first. As there are 3 feet to a yard then 10 feet = 10/3 = 3 1/3 yards. 21 feet = 21/3 = 7 yards.3 1/3 * 7 = 23 1/3 square yards.
To convert square feet to square meters, you need to multiply by 0.0929. The room is 21 ft x 14 ft = 294 square feet. To convert this to square meters, you would multiply 294 by 0.0929, which equals approximately 27.31 square meters.
21 x 21 = 441 square feet
21 feet times 19 feet = 399 square feet
525 square feet (21 x 25)
20x21= 420, so the answer is 420 square feet.
178.5 square feet (8.5 x 21 = 178.5).
21 x 11 = 231 -- There are 231 square feet on the floor. -- There are 231 square feet on the ceiling. -- There are a lot more square feet on the walls, but in order to calculate them, you need to know the height of the room.
