You can put this solution on YOUR website!
side length = x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Use Phytagoras theorem:
\n" ); document.write( "\"x%5E2+%2B+x%5E2+=+16%5E2\"
\n" ); document.write( "\"2x%5E2+=+256\"
\n" ); document.write( "\"x%5E2+=+256%2F2\"
\n" ); document.write( "\"x%5E2+=+128\"
\n" ); document.write( "\"x+=+sqrt%28128%29\"
\n" ); document.write( "\"x+=+sqrt%2864%2A2%29\"
\n" ); document.write( "\"x+=+8sqrt%282%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, the side length is \"8sqrt%282%29\"
\n" ); document.write( "
\n" );
