This example demonstrates how to construct a rectangle and calculate its perimeter and area using GeoGebra. It involves core mathematical concepts such as perimeter, area, rectangle properties, random variables, and probability logic. Key GeoGebra commands used include Random, OrthogonalLine, Intersect, Segment, and Point. Suitable for high school mathematics education, combining geometric constructions with probability and statistics.
