18ft*20ft = 360 square feet
90-ft, minus the width of any gate or other openings in the fence
A minimum of 300 square feet.
20ft² = 1.858m²
20ft long by 11ft wide
12ft*25ft = 300 square feet
18ft*20ft = 360 square feet
If that is 20ft by 20ft then there are 400 square feet
375 square feet
Total square feet: 350.0
90-ft, minus the width of any gate or other openings in the fence
To convert square feet to square meters, you would multiply by 0.0929. Therefore, for a 20ft x 20ft area, you would calculate 20ft x 20ft = 400 square feet. To convert this to square meters, you would multiply 400 by 0.0929, resulting in an area of approximately 37.16 square meters.
