For a rectangle,
\n" ); document.write( " $\"P=2L%2B2W\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"2L%2B2W=124\"$
\n" ); document.write( " $\"L%2BW=62\"$
\n" ); document.write( "and
\n" ); document.write( " $\"L=6%2B3W\"$
\n" ); document.write( "Substituting,
\n" ); document.write( " $\"%286%2B3W%29%2BW=62\"$
\n" ); document.write( " $\"4W=56\"$
\n" ); document.write( " $\"W=14\"$ $\"cm\"$
\n" ); document.write( "Now use either of the equations to solve for $\"L\"$ . \n" ); document.write( "

\n" );
