Özet
Let A be the class of functions f(z) which are analytic in the open unit disk U with f(0) = 0 and f'(0) = 1. Denote the length L(r) of the image curve of vertical bar z vertical bar = r < 1 by f(z) is an element of A. The object of the present paper is to consider L(r) for certain starlike mappings f(z) satisfying some subordination in U.
