1. Question 8:
http://qualifications.pearson.com/co...e_20130614.pdf
I don't know how to split the shape to answer the question.
I have the mark scheme but it does'nt say how to go about answering the question.
2. It's pretty simple. Split the shape into a rectangle and a trapezium. Add their areas. Multiply this by the cost per m^2.

I think the easiest way is to subtract the triangle from the big rectangle which is 80m by 60m.

okay so i did that and i got 180 for the trapezium and 2400 for the rectangle
all together that's 2580

then i did 2580 x 2.56 (the cost) which gave me £6604.8

buuut that's wrong
march scheme says it's 10752

where did i go wrong?

6. Split the shape three ways. Square, rectangle and find the areas. For the triangle its 1/2 x breadth x width. Simple
