In this paper we prove the existence and approximation theorems for positive solutions of a couple of nonlinear first order quadratic hybrid functional differential equations with delay under certain mixed conditions of algebra, geometry and topology. We employ the Dhage iteration method embodied in a hybrid fixed point principle of Dhage (2014) involving the product of two operators in a partially ordered Banach algebra in the discussion. A couple of numerical examples are also provided to indicate the applicability of the abstract results to some concrete problems of quadratic functional differential equations.
