For a rectangle,
\n" ); document.write( " $\"P=2%28L%2BW%29=72\"$
\n" ); document.write( " $\"L%2BW=36\"$
\n" ); document.write( ".
\n" ); document.write( "..
\n" ); document.write( " $\"L=3W\"$
\n" ); document.write( "Substitute,
\n" ); document.write( " $\"3W%2BW=36\"$
\n" ); document.write( " $\"4W=36\"$
\n" ); document.write( " $\"W=9\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"L=3%289%29\"$
\n" ); document.write( " $\"L=27\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
