To get the area of a rectangle, you multiply length x width.
To find the square footage multiply both the length and width of the room. So for 72 feet wide and 156 feet long room the square footage is = 72 feet X 156 feet = 11232 square feet.
225 square feet
To find the square footage of a room, you simply multiply the length of the room (in feet) by the width of the room (in feet). The answer is the square footage of the room (assuming the sides opposite each or are equal in length)
13 * 13 = 169 square feet.
Multiply them together.
It's 176 ft2 Simply multiply the two figures together to get the square footage !
330 square feet
Area is length times width. The floor is 100 square feet.
By multiplication and so 12 times 12 = 144 square feet
You have to multiply the two dimensions to get the area. In this case the answer will be 117 square feet.
A room's dimensions are not dictated by square footage. For example it might be one foot wide and 4400 feet long, or 220 feet long and 20 feet wide. It could assume any shape: oval, round, square, etc. Square footage is a measurement of area.
You multiply the width by the length, thus: 8 feet *12 feet = 96 square feet.
