See my attached demo where you can hand-draw some region (doesn't have to be rectangular) and it will report the area and do some other stuff too, like masking.

Well, that would depend on the area, wouldn't it?
number_of_pixels = width * height;

I don't think so, but you can pass the pixels into hist().
