$\"P=2L%2B2W=230\"$
\n" ); document.write( " $\"L%2BW=115\"$
\n" ); document.write( " $\"A=L%2AW\"$
\n" ); document.write( "But from above,
\n" ); document.write( " $\"W=115-L\"$
\n" ); document.write( " $\"A=L%28115-L%29\"$
\n" ); document.write( "Since the area cannot be less than or equal to zero.
\n" ); document.write( " $\"L%3C115\"$ and $\"L%3E0\"$
\n" ); document.write( " $\"0%3CL%3C115\"$
\n" ); document.write( " \n" ); document.write( "
