This is another video in the measurement, scale and similarity module for Year 11 General Maths (Units 1 and 2) VCE course. Having looked at some really important things, we now go back into the past and recap (once more!) how to the find the perimeter/circumference and areas of the most important shapes in Mathematics. There are lots of worked examples and explanations which everyone will be able to understand. There are summary notes which can also be downloaded from www.maffsguru.com
