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.
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.
Multiply them together.
It's 176 ft2 Simply multiply the two figures together to get the square footage !
approx. 172.5 square feet
330 square feet
By multiplication and so 12 times 12 = 144 square feet
The square footage of the room is determined by the floor dimensions. So if you have a 12 x 20 room the square footage is 240 square feet.
You have to multiply the two dimensions to get the area. In this case the answer will be 117 square feet.
