If the 7 corresponds to lengths then \"4%2F7=w%2F31.5\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"w=4%2A31.5%2F7\"\r
\n" ); document.write( "\n" ); document.write( "\"highlight%28w=18%29\"-------width\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You can find these:\r
\n" ); document.write( "\n" ); document.write( "perimeter \"2%2A31.5%2B2%2A18\"\r
\n" ); document.write( "\n" ); document.write( "area, \"18%2A31.5\"
\n" ); document.write( "
\n" );
