Area and perimeter summary

Area and perimeter summary
When you first learn to find the area of a shape you do it by counting squares. You then learn that you can use formulae to quickly and accurately find the areas of some shapes. Can you remember the formulae and use them reliably? Now find the perimeter and area of all the shapes below (not drawn to scale). Remember to use the correct units of measurement (cm or cm2).
