Measure of the convex hull of a ball and a point
"Sets of finite perimeter and geometric measure theory" F.Maggi, page 264 in the middle of the page ^^' Maybe i formulated it wrong.. It is strange that the book made an error like this

Every convex set is of locally finite perimeter
Thank you very much! For convenience of future readers i add that the same argument that you presented works with the compactness of the sets of finite perimeter: that is If $\{ E_h\}_h$ are of finite perimeter and they satisfies $sup_h P(E_h)<\infty$ and $E_h\subset B_R$ for a certain R Then there exists $E$ a set of finite perimeter s.t. $E_h\to E$ and $\mu_{E_h}\to^{\star}\mu_E$.
