There is 121 square feet in a 11'x11' room.
Imagine a room 25 feet by 13 feet. That room has an area of 25 x 13 or 325 square feet.
13 * 13 = 169 square feet.
multiply the length (in feet) by the width (in feet). For example, if the room is 8 ft by 8 ft, then the room has 16 square feet.
A 30ft x 14ft room = 420 square feet.
The area of the room is 95 square feet.
400 square feet.
The square footage of a 12x27 room is 324 square feet. To find this, you multiply the length (12 feet) by the width (27 feet) of the room.
If it's a square room then the room size is 14 feet by 14 feet
A 10x14 room has an area of 140 square feet (10 feet x 14 feet = 140 square feet).
The square footage of a room that is 12 feet by 23 feet is 276 square feet. This is calculated by multiplying the length (12 ft) by the width (23 ft) of the room.
225 square feet
A 10x13 room would have 130 square feet. This is calculated by multiplying the length (10 feet) by the width (13 feet) of the room to find the total square footage.
A room that is 12 feet by 13 feet is 156 square feet in area
16' x 15' = 240 square feet.
A simple rectangular room 20 feet by 18 feet has 360 square feet.
