  This paper presents bounds for the best approximation, with respect to the
Hausdorff metric, of a convex body $K$ by a circumscribed polytope $P$ with a
given number of facets. These bounds are of particular interest if $K$ is
elongated. To measure the elongation of the convex set, its isoperimetric ratio
$ V_j(K)^{1/j} V_i(K)^{-1/i} $ is used.
