630 ft2
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.
3*5 = 15 square meters
Area of a rectangle is equal to length x width.15 feet x 16 feet = (15 x 16) square feet = 240 square feet
Oh, dude, it's like super simple. The area of a room is just the space inside it, right? So, if you have a 15m² room, the area is 15 square meters. It's like, the size of the floor, man. Easy peasy.
In order to get the square footage you need to take 13' times 15' and you will get the square footage
To calculate the square footage of a room, you multiply its length by its width. For a room that is 15 feet by 26 feet, the square footage is 15 x 26 = 390 square feet.
225 square ft.
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 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
