8cm 5cm Area = 8 x 5 = 40cm 2
A parallelogram can be split up into a rectangle and 2 triangles – each with the same area. 10cm 5cm
If you move one triangle to the other end, you get a rectangle.

The distance around an enclosed shape is called the perimeter. The amount of space enclosed inside a shape is called the area.
What is area? The amount of space that a figure encloses The number of square units that covers a shape or figure. It is two-dimensional It is always.
