For a rectangle,
\n" ); document.write( " $\"P=2L%2B2W\"$
\n" ); document.write( "For this rectangle,
\n" ); document.write( " $\"L=W%2B7.5\"$
\n" ); document.write( "and
\n" ); document.write( " $\"2L%2B2W=35\"$
\n" ); document.write( "Substituting,
\n" ); document.write( " $\"2%28W%2B7.5%29%2B2W=35\"$
\n" ); document.write( " $\"2W%2B15%2B2W=35\"$
\n" ); document.write( " $\"4W=20\"$
\n" ); document.write( " $\"W=5\"$ $\"m\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"L=5%2B7.5\"$
\n" ); document.write( " $\"L=12.5\"$ $\"m\"$ \n" ); document.write( "

\n" );
