you can't straight convert a linear measure to an area measure... missing info.
If the board is 12" wide, then the ratio is one to one. if the board is 6" wide, the linear footage needed would be double. It's a simple ratio.
width of board in inches/12 * length in feet = square feet.
length in feet = square feet * 12 / width
7.5 square feet
A 2x12x12 foot board would not be measured in square feet but cubic feet and there would be 240 feet3
28,350 square feet. (to do this conversion just multiply square yards by nine to get square feet. So, 3,150 x 9 = 28,350 square feet.)
There is no conversion from 3d to 2d.
Divide by 144 to make the conversion. This works out to be 8 square feet.
The conversion is: square feet divided by 0.093 = square meters.122 / 0.093 = ~11.334 m2
square feet x 0.092 = square meters
Conversion: Square metres x 10.7639 = square feet
Divide the square feet by 10.76391
In terms of square feet, 0.376 acres = 16,378.56 square feet.
I cannot provide a conversion chart but the formula is 1 acre = 43560 square feet.
There are 10,330,880 square feet in 3.8 square miles. This conversion can be done by multiplying the number of square miles by the conversion factor of 27,878,400 square feet per square mile.
The conversion formula for square feet to square meters is: square feet x 0.092 = square meters
7.5 square feet
48 square feet.
Use this conversion: acres x 43,560 = square feet
You can't convert length to area.
