Last updated 03 May 2014, created 17 October 2010, viewed 10,980

Forming expressions for area and perimeter and simplifying to show equivalence. There is a great deal of scope for differentiation here, with two activities which take the idea further (The last one is not my own, but from a resource called 'Materials to Support able mathematicians in KS3') More…Includes application of trigonometry ratios in finding the general rule for areas of regular polygons.

This is great thanks! As a slight niggle for shape 5 e must be 3 as 4+2e =10, then stating that the area is 24 is confusing, I changed the question to "can you find the area?". Thankyou for sharing.
