Area and Perimeter of Rectilinear Figures

Finding the area and perimeter of composite shapes made of rectangles.

Key Questions

  1. 1Why can two shapes have the same perimeter but different areas?
  2. 2How can we decompose a complex shape into simpler rectangles to find its total area?
  3. 3If the area of a square is 36 square centimeters, how can we work backwards to find its perimeter?
