We'll need to know the units. If that's 900 feet by 12 feet, the square footage is 10,800. If it's some other unit, tell us what it is.
900 of them. Get extra for breakage.
75-ft x 12-ft = 900 square feet
12 feet times 12 feet = 144 square feet
12 feet x 12 feet = 144 square feet.
Area calculation: 30 inches by 30 inches = (30 x 30) square inches =900 square inches or, if you want square feet instead: 12 inches x 12 inches (1 square foot) = 144 square inches Take your 900 square inches and divide by 144 to get square feet. 900 / 144 = 6.25 square feet
If the given dimensions are in feet then: 12 times 75 = 900 square feet
900 of them. Get extra for breakage.
75-ft x 12-ft = 900 square feet
900 square feet. Multiply length by width - the result is the area in square feet.
Just multiply the two together to get area. This would be 900 square feet.
75, 6.25 12 x 12 ft tiles to cover surface of 900 ft2
Just multiply the two numbers together. You have 900 square feet.
12 feet times 12 feet = 144 square feet
12 feet x 12 feet = 144 square feet.
There are: 12 times 12 = 144 square feet
12 feet x 12 feet = 144 square feet.
12 square feet = 1.33333333... square yeards
