\n" ); document.write( "\"A=LW\"\r
\n" ); document.write( "\n" ); document.write( "the length increase \"30\"% =>\"L%2B0.30L=1.30L\"
\n" ); document.write( "the width increase \"20\"%=>\"W%2B0.20W=1.20W\"\r
\n" ); document.write( "\n" ); document.write( "\"A1=%281.30L%29%281.20W%29\"
\n" ); document.write( "\"A1=1.56+LW++\"\r
\n" ); document.write( "\n" ); document.write( "difference\r
\n" ); document.write( "\n" ); document.write( "\"A1-A=1.56LW+-LW=%281.56+-1%29LW=+0.56LW+\"\r
\n" ); document.write( "\n" ); document.write( "=> increase of \"56\"%
