J. Anal. Appl. 13(1):64-69, 2017), we establish some weighted Ostrowski type inequalities for co-ordinated convex functions in a rectangle from the plane R-2. Moreover, as special cases of our main results, we give some weighted Hermite-Hadamard type inequalities. The results given in this paper provide generalizations of some result established in earlier works.en10.1186/s13660-021-02745-1info:eu-repo/semantics/openAccessOstrowski Inequality; Hermite-Hadamard-Fejer Inequality; Co-Ordinated Convex; Integral InequalitiesIntegral Inequality; RectangleArticle202212-s2.0-85122287969WOS:000739401600001Q2Q1
