You can put this solution on YOUR website!
If you have an area of a square, then you can find the length of the sides. This is because the area is given as
\n" ); document.write( "\"A=x%5E2\" where x is the length of the side
\n" ); document.write( "So if you take the square root of both sides
\n" ); document.write( "\"sqrt%28A%29=sqrt%28x%5E2%29\"
\n" ); document.write( "\"x=0%2B-sqrt%28A%29\"it's equal to plus-minus square root of A, but we'll ignore the negative answer (a negative length doesn't make sense)
\n" ); document.write( "When you take the square root of the area, then you'll find the length of the sides.
\n" ); document.write( "
