30' * 12' = 360 sq ft
30 feet by 28 feet equals 840 square feet. 30 inches by 28 inches equals 840 square inches, or 5.833 square feet.
600 square feet
810
30 feet x 12 feet is 52 square yards 30 yards x 12 yards is 468 square yards
Assuming that 12 x 12 is 12" x 12" (one square foot), then 30 one-square-foot tiles would cover 30 square feet.
15 square feet.
9 square feet = 1 square yard Area of the floor = 12' x 30' = 360 square feet = 40 square yards
Multiply by 9 to make the conversion. This works out to be 270 square feet.
3 x 30 = 90 square feet. 1 square foot = 144 square inches (12 x 12) So 90 square feet = 12,960 square inches
To find the area multiply the length by the width.In this case multiply 30 by 46. 30 x 46 equals 1,380.Therefore the area of a square measuring 30' x 46' equals 1,380 square feet.
2.5 feet
30' x 12' is 360 square feet or about 33.445 square meters.
