This question cannot be answered sensibly. A square foot is a measure of area, with dimensions [L2]. A linear foot is a measure of distance, with dimensions [L]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
150 x 90 = 13,500 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.
100-ft x 90-ft = 9,000 square feet
3 x 30 = 90 square feet. 1 square foot = 144 square inches (12 x 12) So 90 square feet = 12,960 square inches
90 square feet. Multiply length by width - the result is the area in square feet.
You can't calculate linear footage based on square yardage alone. If you meant square footage it will cover 810 sq. ft..
90 X 144 (INCHES PER SQ FT) = 12,960 INCHES. 12,960 INCHES DIVIDED BY 12 (INCHES PER LINEAR FT) = 1080 LINEAR 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.
You can't. A square foot is a measure of area. a regular, linear foot is a measure of length. The two units are completely incompatible.
300 feet is a measurement of DISTANCE, while square feet is a measure of AREA. However, 300 averaged-sized human feet would cover about 100 square feet of area, although the owners of said feet would have to be VERY friendly. It is impossible to determine area from a single linear measurement. You need 300 feet BY some other linear measurement to calculate area.
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.
100-ft x 90-ft = 9,000 square feet
90 square feet
There's about 969 square feet in 90 square meters
