L = W + 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(L + 6)(W + 6) - LW = 300\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "6L + 6W + 36 = 300\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "L + W = 44\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ (W + 4) + W = 44 ___ 2W = 40 ___ W = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ L = (20) + 4 = 24
\n" ); document.write( "
