2013-10-14 06:49
This GeoGebra applet demonstrates the calculation of perimeter and area for polygons with a missing piece, such as L-shaped or notched rectangles. Using polygon translation and segment construction, it visually illustrates how irregular notched shapes can be transformed into regular rectangles for perimeter comparison, and how to calculate the actual area using geometric decomposition.
