w = l/2, wis width, l is length
\n" ); document.write( ":
\n" ); document.write( "184 = ((w+4) * (l+4)) - (l*w)
\n" ); document.write( ":
\n" ); document.write( "184 = wl+4l+4w+16 - wl
\n" ); document.write( ":
\n" ); document.write( "184 = 4l +4w +16
\n" ); document.write( ":
\n" ); document.write( "substitute for w
\n" ); document.write( ":
\n" ); document.write( "184 = 4l +4*(l/2) +16
\n" ); document.write( ":
\n" ); document.write( "184 = 4l +2l +16
\n" ); document.write( ":
\n" ); document.write( "6l = 168
\n" ); document.write( ":
\n" ); document.write( "l = 28
\n" ); document.write( ":
\n" ); document.write( "w = 14
