Slobodan,

regarding a minor aspect of your question:

A pixel has no area/extension.
It is an ideal mathematical point and its value is a number in the
computer memory.

The pixel-square on a computer display is a kind of coarse interpolation
approach to make the spatially discrete pixel array continuous and
visible. It is not per se accessible for computations.
