The area of a rectangle is,
\n" ); document.write( " $\"A=L%2AW\"$
\n" ); document.write( "But you also know that,
\n" ); document.write( " $\"W=0.25%2AL=L%2F4\"$
\n" ); document.write( " $\"L=4W\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"A=4W%2AW\"$
\n" ); document.write( " $\"A=4W%5E2\"$ \n" ); document.write( "

\n" );
