70 square foot.
400 square feet
Read your own question! The square footage is 20!
15 * 20 = 300 square feet.
12*20 = 240 square feet.
To find the square footage of a room, you multiply the length by the width. For a room that is 20 feet by 50 feet, the calculation would be 20 x 50 = 1,000 square feet. Therefore, the square footage of the room is 1,000 square feet.
25 square feet.
20 X 30 = 600 square feet.
500 square feet (25 x 20 = 500).
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.
20ft * 15ft = 300 square feet.
30 feet x 20 feet = 600 square feet.
In terms of square footage, 20 acres = 871,200 square feet.
