p = 460 = 2w+2l
\n" ); document.write( "l = 3w-40
\n" ); document.write( "460=2w+2(3w-40)
\n" ); document.write( "460 = 2w + 6w - 80
\n" ); document.write( "460+80 = 8w
\n" ); document.write( "540 = 8w
\n" ); document.write( "w = 67.5
\n" ); document.write( "l = 3(67.5)-40 = 162.5
\n" ); document.write( "
