Area and Perimeter of Composite Shapes

Students calculate the area and perimeter of composite 2D shapes by decomposing them into simpler geometric figures.

Key Questions

  1. How can complex shapes be broken down to calculate their area and perimeter?
  2. What are the formulas for the area and perimeter of basic shapes like rectangles, triangles, and circles?
  3. How does the choice of decomposition affect the calculation process?
