The floor area of a building12 feet x 28 feet is 336 square feet.
336 square feet (12 x 28 = 336).
12 ft * 28 ft = 12*28 sq ft = 336 sq ft
Total square feet: 336.0
(12-ft x 21-ft) / (9 square feet per square yard) = 28 square yards
37.33 sq yd
12' x 21' (252 square feet) = 28 sq. yards.
784 square feet
Multiply the two dimensions to get the area. The calculation will give you 252 square feet which converts to 28 square yards.
Assuming that the room is 12 FEET by 28 FEET the area is 336 square feet.
The answer is 238. All you do to fund the square feet is multiply the to together
To calculate the square footage of a room that measures 28 feet by 12 feet, multiply the length by the width: 28 ft × 12 ft = 336 sq. ft. Therefore, the room is 336 square feet in size.
3.11 square yards = 28 square feet.
