This example demonstrates how to calculate the area of polygons through geometric construction. Key mathematical concepts include polygons, vectors, and coordinate geometry. Using GeoGebra commands such as Polygon and objects, multiple polygons can be constructed and analyzed. Suitable for middle school and above students or teachers.
