13 ft * 90 ft = 13*90 sq feet = 1170 sq feet.
90 x 130 = 11,700 square feet.
150 x 90 = 13,500 square feet
There are: 90*49.5 = 4455 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.
100-ft x 90-ft = 9,000 square feet
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 square feet
90 * 330 = 29700 sq ft
There's about 969 square feet in 90 square meters
8.36 square meters.
90
To get square footage you multiply the width by the length. In this case 90 times 50 equals 4500 sq. feet
