3x and 4x
\n" ); document.write( "width = 3x
\n" ); document.write( "length = 4x
\n" ); document.write( "w*l = area
\n" ); document.write( "3x*4x = 108
\n" ); document.write( "12x^2 = 108
\n" ); document.write( "x^2 = 9
\n" ); document.write( "x = +- 3
\n" ); document.write( "width = 9cm
\n" ); document.write( "length = 12cm \n" ); document.write( "
\n" );
