We consider the possibility to use the areas of two-simplexes, instead of
lengths of edges, as the dynamical variables of Regge calculus. We show that if
the action of Regge calculus is varied with respect to the areas of
two-simplexes, and appropriate constraints are imposed between the variations,
the Einstein-Regge equations are recovered.
