Perimeter and Area of a Rectangle by Alaa (ALEX) Selim

This example demonstrates how the area and perimeter of a rectangle change as its length and width vary. Key mathematical concepts include area, perimeter, and multiplication. Using GeoGebra commands such as Intersect, OrthogonalLine, and Polygon, the example allows for dynamic observation of the rectangle's changes. Suitable for middle school and above students learning geometry and algebra.
