Fencing Problem Maths Coursework!Watch
i have this maths coursework, where theres a fencing 'problem' basically i need to know how to work out the area of octagons, pentagons, hexagons etc. i just cant do it!
please help me!
+ what has more area? a circle or a square/rectangle?
Do the same thing with 4 sided shapes - rectangles, squares, parallelograms (split into triangles to find the area) if you're feeling clever etc etc
By this point you should see a pattern emerging for each No of sides - ie a certain type of shape will have the greatest area.
Predict this and then work out the area for some shapes with more sides - pentagon, hexagons octagons etc (by splitting into triangles)...and see if changing the number of sides increases the area you can get.
Contains all the formulae you should need for areas and perimeters
