Filled area inside a closed curve

Consider a closed curve that contains some holes. I would like to show
that the filled area can be calculated by subtracting the area of
holes from area of the curve. Is there any theorem that can prove it?
I do not need to calculate the area.
To clarify my question I provide a shape for my question
Thanks a lot.
