The area of the room is the result of multiplying the lengths of two walls. So if your room is 400 square feet, the walls might be 20 ft. by 20 ft., 10 ft. by 40 ft., or any other combination that would multiply out to be 400.
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.
400 square feet, at the school I went to.

400 square feet.
Any size room where the length in feet times the width in feet equals 400. One example would be a 20' x 20' room.
A room 20 feet by 20 feet will have a floor that size.
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.

25 x 16 = 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
400 square feet, at the school I went to.
A room measuring 20' x 20' = 400 square feet
That would be 400 square feet. A square yard is 9 square feet. Divide 400 by 9 and you get 44.4 Square yards.
