Just multiply the two measurements: 20 x 25 = 500 sq feet.
Ah, what a lovely question! To find the square footage of a room, you simply multiply the length by the width. In this case, a 12 x 20 room would have a square footage of 240 square feet. Just imagine all the happy little memories you can create in a space like that!
if you want the square footage, 15 ft x 20 ft is 300 square feet
20 X 30 = 600 square feet.
18 ft X 20 ft = 360 Square feet
For 9 ft x 20 ft = 180 ft²
20 x 20 = 400 The room has 400 square feet on the floor, 400 square feet on the ceiling, and (80 x height of the room) square feet on the walls.
20 x 30= 600ft
two hundred and forty 12 x 20 = 240
Just multiply the two measurements: 20 x 25 = 500 sq feet.
To calculate the square footage of a room, you multiply its length by its width. For a room that is 21 feet long and 14 feet wide, the square footage would be 21 x 14 = 294 square feet.
Easy to do. Just multiply the two dimensions: 15 x 20 = 300 square feet.
Multiply 37 x 30 to get the square footage.
