3x*5x = 60\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "15x^2 = 60\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x^2 = 60/15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x^2 = 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = sqrt(4)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-------------------------------------------------------\r

\n" ); document.write( "\n" ); document.write( "3x = 3*2 = 6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "5x = 5*2 = 10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The rectangle has a length of 10 and a width of 6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Notice how 6:10 reduces to 3:5 (divide both parts by 2)\r
