Area of a Rectangle 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.
