If the numbers are in feet then 86 times 20 = 1720 square feet
20 x 19 = 380 square feet.
1 foot = 0.3048 square meters 19 feet X 20 feet = 35.3031552 square meters
50 ft * 20 feet = 1000 square feet.
380 sq. feet
20' x 6' = 120 square feet.
2,000 square feet (20 x 100 = 2,000).
280 (square meters) = 3,013.9 square feet.
2.78 square feet.
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
