The perimeter of a rectangle is,
\n" ); document.write( " $\"P=2%2A%28L%2BW%29\"$
\n" ); document.write( "The area of a rectangle is,
\n" ); document.write( " $\"A=L%2AW=32\"$
\n" ); document.write( "Let one side be $\"x\"$ , say $\"L=x\"$ ,
\n" ); document.write( " $\"x%2AW=32\"$
\n" ); document.write( " $\"W=32%2Fx\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"P=2%28x%2B32%2Fx%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
