You can't. One is length the other is area.
To convert the area of a 100 ft by 100 ft square into hectares, first calculate the area in square feet: 100 ft × 100 ft = 10,000 square feet. Next, convert square feet to hectares using the conversion factor: 1 hectare = 107,639 square feet. Therefore, 10,000 square feet is approximately 0.092 hectares.
1 square = 100 sq ft = 9.29 sqm
100 ft * 100 ft = 10000 square feet.
How to convert 12 ft x 14 ft into square feet
To find the area of a square, you multiply the length by the width. In this case, 100 ft x 100 ft equals 10,000 square feet. This is because 100 ft multiplied by 100 ft is equal to 10,000 square feet.
Divide by 9 to convert between the two. In this case the answer is 11.11 square yards.
To convert feet to acres, you must first convert the dimensions to acres. One acre is equal to 43,560 square feet. Therefore, the area of 200 ft by 300 ft is 60,000 square feet. To convert this to acres, divide by 43,560, resulting in approximately 1.38 acres.
Multiply by 9.
1 ft^2 = 144 in^2
1 acre = 43,560 square feet.100-ft x 100-ft = 10,000 square feet = 0.2296 acre (rounded)
100-ft x 90-ft = 9,000 square feet
100-ft x 200-ft = 20,000 square feet
