Activity:

In our lesson today we are building on yesterday’s work of calculating perimeters of rectangles so today we are going to calculate the perimeter of polygons.

A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides.  Click on this link below to learn more about polygons.
