For a rectangle,
\n" ); document.write( " $\"A=L%2AW\"$
\n" ); document.write( "In this case,
\n" ); document.write( " $\"L%2AW%3E=630\"$
\n" ); document.write( "and
\n" ); document.write( " $\"L=6%2BW\"$
\n" ); document.write( " $\"%286%2BW%29W%3E=630\"$
\n" ); document.write( " $\"W%5E2%2B6W%2B9-630%3E=9\"$
\n" ); document.write( " $\"%28W%2B3%29%5E2%3E=639\"$
\n" ); document.write( " $\"W%2B3%3E=sqrt%28639%29\"$
\n" ); document.write( " $\"W%3E=sqrt%28639%29-3\"$
\n" ); document.write( "or approximately,
\n" ); document.write( " $\"W%3E=22.278\"$ cm
\n" ); document.write( "Then
\n" ); document.write( " $\"L%3E=28.278\"$ cm
\n" ); document.write( "and the area,
\n" ); document.write( " $\"A%3E=630\"$ \n" ); document.write( "

\n" );
