$\"L=3W\"$
\n" ); document.write( "For a rectangle,
\n" ); document.write( " $\"P=2%28L%2BW%29=64\"$
\n" ); document.write( " $\"L%2BW=32\"$
\n" ); document.write( "Substituting,
\n" ); document.write( " $\"3W%2BW=32\"$
\n" ); document.write( " $\"4W=32\"$
\n" ); document.write( " $\"W=8\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"L=3%288%29\"$
\n" ); document.write( " $\"L=24\"$
\n" ); document.write( "For a rectangle,
\n" ); document.write( " $\"A=L%2AW\"$
