x^2+(2x)^2=10
\n" ); document.write( "x^2+4x^2=10
\n" ); document.write( "5x^2=10
\n" ); document.write( "x^2=10/5
\n" ); document.write( "x^2=2
\n" ); document.write( "x=sqrt2
\n" ); document.write( "x=1.414 ans. for the shortest side.
\n" ); document.write( "2*1.414=2.828 ans. for the longer side.
