In this paper, we first obtain some new Fejer type inequalities for products of two convex mappings. Moreover, by applying these inequalities for Riemann-Liouville fractional integrals, we establish some Fejer type inequalities involving Riemann-Liouville fractional integrals. The most important feature of our work is that it contains Fejer type inequalities for both classical integrals and fractional integrals.
