420 square feet (28 x 15 = 420).
The formula for calculating square footage is a=S2 (a = area and s = side) Example, to calculate the square footage of a room that is 15 feet wide and 12 long, you would multiply 15 x 12, which will give you the square footage.
Length x width = square footage
50. Length times width equals the square footage.
For square footage (area) you only have two measurements. So a carpet 4 ft x 4 ft has a square footage of 16 square feet. And a carpet of 4 ft x 8 ft has a square footage of 32 square feet. Three measurements like 4 ft x 4 ft x 8 ft give you cubic footage, or volume. So the volume of a container that size would be 128 cubic feet.
1,560 square feet.
225 square feet (15 x 15 = 225).
20 x 15 = 300 square feet
225 square ft.
15 x 15 = 225 square feet
6' x 2.5' is 15 square feet.
If you mean 75 feet x 15 feet then the square footage is 1,125 square feet.
if you want the square footage, 15 ft x 20 ft is 300 square feet
13 feet times 28 feet = 364 square feet
The formula for calculating square footage is a=S2 (a = area and s = side) Example, to calculate the square footage of a room that is 15 feet wide and 12 long, you would multiply 15 x 12, which will give you the square footage.
15 feet x 15 feet = 225 square feet.
240 square feet. (16 x 15 = 240)
375 square feet.(area = length x width)
