By inspection, the z centroidal axis of the entire cross-section passes through the centroids of the left and right vertical flanges and the horizontal web. Calculate Iz, fl the moment of inertia for the left vertical flange about the z centroidal axis. Note that each flange is rectangular with dimensions 16mm x 170mm, so the moments of inertia for the left and right vertical flanges are identical.
