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
To determine how many 12-inch by 12-inch pavers are needed for a walkway area of 30 square feet, first convert the dimensions of the paver to square feet. Each paver is 1 square foot (12 inches x 12 inches = 144 square inches, which equals 1 square foot). Therefore, to cover 30 square feet, you would need 30 pavers, since each paver covers 1 square foot.

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 square footage of a rectangle, you multiply the length by the width. In this case, 30 feet multiplied by 40 feet equals 1200 square feet. Therefore, there are 1200 square feet in a 30'x40' area.
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.
