Rectangle area, \"8%2A6%2Acm%5E2\";
\n" ); document.write( "Including the border, total area, \"%288%2B2%2A1.5%29%286%2B2%2A1.5%29%2Acm%5E2\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The difference is the border area alone.
\n" ); document.write( "This is why those two number expressions were not computed:
\n" ); document.write( "\"%288%2B2%2A1.5%29%286%2B2%2A1.5%29-8%2A6\"
\n" ); document.write( "\"%288%2B3%29%286%2B3%29-8%2A6\"
\n" ); document.write( "\"8%2A6%2B3%2A8%2B3%2A6%2B9-8%2A6\"----presence of additive inverse
\n" ); document.write( "\"3%2A8%2B3%2A6%2B9\"
\n" ); document.write( "\"3%288%2B6%29%2B9\"
\n" ); document.write( "\"3%2A14%2B9\"
\n" ); document.write( "\"42%2B9\"
\n" ); document.write( "\"highlight%2851%29\"------area of the border\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You can go back and compute the total border plus rectangle area.
\n" ); document.write( "
\n" );
