L = 2W
\n" ); document.write( ".
\n" ); document.write( "P = 2(L+W)
\n" ); document.write( "P = 54
\n" ); document.write( ".
\n" ); document.write( "substitute
\n" ); document.write( ".
\n" ); document.write( "2(L+W) = 54
\n" ); document.write( "2(2W + W) = 54
\n" ); document.write( "4W +2W = 54
\n" ); document.write( "6W = 54
\n" ); document.write( "W = 9
\n" ); document.write( ".
\n" ); document.write( "L = 2W
\n" ); document.write( "L = 2(9) = 18
\n" ); document.write( ".
\n" ); document.write( "Check the perimeter
\n" ); document.write( ".
\n" ); document.write( "2(18+9) = 2(27) = 54
\n" ); document.write( "Correct.
\n" ); document.write( ".
\n" ); document.write( "Answer: Length = 18; Width = 9.
\n" ); document.write( ".
\n" ); document.write( "Done.
