90 x 130 = 11,700 square feet.
There are: 90*49.5 = 4455 square feet
150 x 90 = 13,500 square feet
To find how many square feet are in an area, multiply the length time the width. 20 x 90 is 180 square feet.
50 ft x 90 ft = 4500 square feet. One square yard (3 ft x 3 ft) = 9 square feet. Therefore, 4500 square feet = 500 square yards.
3 x 30 = 90 square feet (90 ft2).
100-ft x 90-ft = 9,000 square feet
