20 X 30 = 600 square feet.
200 square feet
20 X 16 = 320, 320 square feet
If the given dimensions are in feet then 24 times 20 = 480 square feet
There are: 20 times 9 = 180 square feet
400 square feet.
The question does not give the units of measurement for the room's size. Assuming they are feet, the square footage is 20*12 = 240 square feet.
A room 20 feet by 20 feet will have a floor that size.
20 = 5 x 4
Any size room where the length in feet times the width in feet equals 400. One example would be a 20' x 20' room.
400 square feet
A room measuring 20' x 20' = 400 square feet
There are 44.44 square yards in a room that is 20 feet x 20 feet (400 square feet). 20 feet x 20 feet = 400 square feet 400 square feet x 0.111111111 square yards/1 square foot = 44.44 square yards 1 square foot = 0.111111111 square yards
18 ft X 20 ft = 360 Square feet
12*20 = 240 square feet.
20 ft * 500 ft = 10000 square feet. Rather a large room!
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.
