\n" ); document.write( "----
\n" ); document.write( "Let each of the sides of the square be \"x\":
\n" ); document.write( "Equation:
\n" ); document.write( "x^2 + x^2 = 40^2
\n" ); document.write( "------
\n" ); document.write( "2x^2 = 1600
\n" ); document.write( "x^2 = 800
\n" ); document.write( "x^2 = 400*2
\n" ); document.write( "x = 20*sqrt(2)
