This week we began chapter 5 and we started with an activity on finding the areas of iregular polygonsand shapes.Some of the polygons/shapes were combinations of triangles, trapezoids, rectangles, and circles and so in order to find the areas of one such example one would use the appropriate polygon.For each of the shapes one could use a rectangle to find the area,which is why finding area is measured in square units.This directly led us into the topic of RAM or rectangular approximation method.
