Struggling with this question and so are my mates.

Attached is the Graph.

The line PQ has equation y=2x+4

(a) Find, without using calculus, the area of the shaded trapezium shown in the diagram.

(b) Express the area of this trapezium as a definite integral.

(c) Evaluate this integral

I just dont know where to go about tackling this question at all, I feel its the english putting me off. If anyone can help me to find the solutions to this question it will help me and assure I know what I am doing when I face similar questions in future.

Many Thanks

PS. The Q should be right at the end of the line with P..... the digit close to the P is a 0 not a Q, sorry about that
