The lot was actually (157 +2) x (157 - 2) = 159 x 155
\n" ); document.write( "He thought the lot was \"157%2A157+=+24649\" ft2
\n" ); document.write( "But it actually was \"159%2A155+=+24645\" ft2
\n" ); document.write( "It was \"24649+-+24645+=+4\" ft2 less area than he thought
\n" ); document.write( "
\n" );
