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

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
3 x 30 = 90 square feet. 1 square foot = 144 square inches (12 x 12) So 90 square feet = 12,960 square inches
Multiply by 9 to make the conversion. This works out to be 270 square feet.
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.
