Read your own question! The square footage is 20!
The square footage of the room is determined by the floor dimensions. So if you have a 12 x 20 room the square footage is 240 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.
400 square feet
That's a total of 20 square yards.
if you want the square footage, 15 ft x 20 ft is 300 square feet
12*20 = 240 square feet.
18 ft X 20 ft = 360 Square feet
20 X 30 = 600 square feet.
20 ft * 500 ft = 10000 square feet. Rather a large room!
