        • This is one in a series of Powerpoint slideshows to
          illustrate how to calculate the area of various 2-D
          shapes.
        • Start with the Rectangle, then move onto the
          Parallelogram.
        • After that select any of Triangle, Trapezium and
          Circle.
        • Please feel free to copy and modify any of these
          slide shows, but make sure you acknowledge the
          author when doing so.
