Areas are two dimensional structures of the space. The area can expand endlessely or be limited and closed. Such as for example the surface of a sphere.  Here one can differentiate between levels, bended and curved areas. The area content would contain a certain number of unit squares. The geometry of the area content is handled with geometric figures. Through this known curves in the limited space can with the help of an integration calculus be ascertained. Approximate vales can be supplised with this graphics method. Likewise with the application of a planimeter or the process of cutting out areas on paper and the paper cut outs of a square unit can be used to compare.
