Please help me..coordinate geometry?
Hello, I have attached the question with my working on here:
I need help for (c) only, I can do part (d). I have done (a) and (b) since you need those information to solve (c), you can see the second picture.
Here is the graph: https://www.desmos.com/calculator/sfid3lilul
Thanks in advance

Area of the trapezium is |OA|(|OC|+|AB|)/2.
This is the perpendicular height × the average of the lengths of the parallel sides.
As you have already shown yourself capable of the other parts of the question, I will call that the "help" you asked for, and not insult you by performing the calculations.
