$\"A+=++81+-+72+x+%2B+16+x%5E2+=+%289-4x%29%5E2\"$ \r
\n" ); document.write( "\n" ); document.write( "==> $\"s+=+sqrt%28%289-4x%29%5E2%29+=+abs%289-4x%29\"$ \r
\n" ); document.write( "\n" ); document.write( "==> Perimeter is $\"P+=+4abs%289-4x%29\"$ \r
\n" ); document.write( "\n" ); document.write( "If x = 1, P = 20,
\n" ); document.write( "If x = 2, P = 4,
\n" ); document.write( "If x = 3, P = 12,
\n" ); document.write( "If x = 4, P = 28, etc., ...\r
\n" ); document.write( "\n" ); document.write( "Therefore the least possible measure for the perimeter of the square is 4. \n" ); document.write( "
