Measure the length and width of the floor in a square or rectangular room, and multiply the figures together to get the floor area in square feet. For example, in a room that is 10 feet wide and 18 feet long, the area would be 10 multiplied by 18 to obtain 180 square feet.
What is the formula of square feet?
To calculate the area of a room in square feet, measure the length and width of the room in feet, then multiply these figures together to give an area in ft². For example, a room measuring 12 ft x 15 ft would be described as having an area of 180 ft² (12 x 15 = 180).
How many square feet is a 15 by 15 room?
We will use a room that is 10 ft x 15 ft as an example in all of our room scenarios: This is the simple equation: Length (ft) x Width (ft) = Square Footage. Example:
10 ft x 15 ft = 150 sq.
