Surface area of a convex hull in 3D

Trying to calculate the surface area of a convex hull in 3D, using CGAL. I have looked at the user manual (http://doc.cgal.org/latest/Convex_hull_3/index.html#Chapter_3D_Convex_Hulls) and have not found any material covering this. I have tried to use polygon_area_2d to calculate the area of the convex hull facets, but have not been successful. Has anybody successfully calculated the area of a 3D convex hull/any suggestions?

Using this example, you compute a triangulation of the convex hull. Them iterating over all the facets of the polyhedron, you can compute the area of each triangle and get the result.
