180 sq ft if 12 X 15 is actually 12 ft X 15 ft. Otherwise anything you like.
If the room is square, then the area is the square of the length of any side.The length of any side is the square root of the area = sqrt(225) = 15.
try multiplying 11 by 15 ....
3*5 = 15 square meters
15 meters squared is the area of the room. You find area by multiplying the length of the room times the width. The result is square meters or feet.
In order to get the square footage you need to take 13' times 15' and you will get the square footage
The question does not give the units of measurement for the room's size. Assuming they are feet, the square footage is 12*15 = 180 square feet.
225 square ft.
225 square feet
if you want the square footage, 15 ft x 20 ft is 300 square feet
approx. 172.5 square feet
135
15 *60 = 900
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.
330 square feet
15 x 15 = 225 square feet
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. (15 + 18 + 15 + 18) x 15 = You do the math.
