To find the area of a square, you multiply the length by the width. In this case, 90 ft x 90 ft equals 8100 square feet. This is because each side of the square is 90 feet long, so the total area covered by the square is 8100 square feet.
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.
3 x 30 = 90 square feet (90 ft2).
100-ft x 90-ft = 9,000 square feet
90 square feet
There's about 969 square feet in 90 square meters
90 * 330 = 29700 sq ft
Area is not measured in feet, but square feet. Assuming you mean an area of 90 feet by 63 feet, this is equal to 90 x 63 = 5670 square feet.
8.36 square meters.
