Could some one please explain how to calculate the area, just the area i know how to work out the charge from there... Do i have to count every single little block?

You need to fragment it, there is no other way. Turn it to several trapeziums and then find are of each and add all together. The more little trapeziums you make the more accurate your answer is.

Thanks i turned them into rectangles and triangles found it much easier... How many papers have you done? Have you found any general trend?

I haven't done much I have found trends though. 2008-2010 repeat 2011-2012. I will be seeing these in depth today. I am covering the papers chapter wise, i find it takes less time. Revise a chapter to all the numbers and it's good
