Can someone help me?

Hi, I want to ask how to find the centre of weight in this cross-section? This section is complex. I need the centre because it is necessary if you want to calculate I (inertion moment) of this section.

Here is a more generalized way of calculating the center of mass using integrals.

    Another method attached. Not as neat as Werner's, but might help with understanding.
