Set L = length
\n" ); document.write( "W = width
\n" ); document.write( "L = 3W
\n" ); document.write( "The perimeter of a rectangle is 2W + 2L ( two short sides and two long sides )
\n" ); document.write( "Substituting 3W for L
\n" ); document.write( "2W + 2(3W)
\n" ); document.write( "2W + 6W
\n" ); document.write( "8W
\n" ); document.write( "
\n" );
