    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?

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