You forget to post your solution! Once you do I am sure that someone would go over it for you.

This is clearly not your attempt, it is the marking scheme. So exactly where do you get stuck?
I would start (a) with a diagram for each part, shading in the area required. That will help you think what to do. Come back after you've done that.

I got the first parts right I just didn’t know how to attempt part b that’s why I have send in the marking scheme

Draw a diagram for (b). Shade in the appropriate area. You will need to work backwards for this one.
