a geometric boundary is a political boundary defined and delimited as a straight line or an arc.
A geometric boundary refers to a division between two areas of land based on physical features such as mountains, rivers, or latitude and longitude lines. These boundaries are usually easily identified on a map due to their clear and distinct geometric characteristics.
The boundary between the two properties was marked by a stone wall.

Canada forms the northern boundary of the United States.
No, the Alps are not a divergent boundary. The Alps are a mountain range formed from the collision of the African and Eurasian tectonic plates, a result of convergent boundary activity.

A region based on political boundaries is a formal region.
the continuous line forming the boundary of a closed geometric figure
No, it is not. Line can be a verb (to outline, or to add a lining), or a noun (marking, geometric segment, or boundary).
the enclosing boundary of a curved geometric figure, esp. a circle. the distance around a circle
A perimeter is the continuous line that forms a closed boundary around a geometric shape.
Strictly speaking, the only geometric item that has neither length nor width is a "point", but as such, it is not considered a "figure". A geometric figure is defined as a "set of points". I suppose a point could be thought of as a set containing only one element, but that rather contradicts the intention of the definition where it refers to points in the plural.As Euclid defined it: A figure is that which is contained by any boundary or boundaries.
The perimeter is the continuous line forming the boundary of a closed geometric figure. Think of walking around a football field. The distance you travel is the sum of the four sides.
Geometric
There aren't any. Geometric is an adjective and you need a noun to go with it before it is possible to consider answering the question. There are geometric sequences, geometric means, geometric theories, geometric shapes. I cannot guess what your question is about.
If, by geometric number (?) you mean geometric mean, then the answer is 40.
