You can calculate the number of square feet in a two-dimensional rectangle by multiplying the length of one of the short sides by the length of one of the long sides. 9' x 12' = 108 square feet
180 square feet. Just multiply length by width - the answer is the square footage.

It I'd 12 multiplied by 9 aka 108.
113 ft
The square footage would be 25 times 12 or 300 square feet.
144 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.

Square footage is length times height. In this case measure the entire length around the room and multiply it by the height of the wall. Assuming the 11 is the length of 2 walls, the 12 is the length of the other two walls and the 9 is the height of the walls the equation would be (11 + 12 + 11 + 12) x 9 = You do the math.
