 <p style="margin:12px">Because the square is the basis of area calculation. That is why we use square units. 
 <br>
 The only problem with that was that the circle is not square. I have figured that the circle can be cut into four and then I get four right angles that can be aligned with the vertices of a square.

 Something that the one would assume of the conventional geometry. There are several geometry concepts, but there's a popular one that they teach in schools and online.

-That starts with that "a point is a zero-dimensional entity", "the line has no thickness" and states that "the ratio between the circumference and the diameter of a circle is π", "the volume of a sphere is 4 / 3 × π × r³", "the volume of a cone and a pyramid is base × height / 3", and all that is "rigorously proven via calculus".

 They call that Euclidean geometry. I primarily regard my framework as a fix of the conventional one.
