It’s a bit of mess, but struggled with question b and c.

Your "method" is mostly correct. But your numbers are not. Please do it over, methodically and cleanly and repost.

I would calculate the area of the quadrilateral by dividing into 2 triangles whose sides will be known (after solving a and b) and Heron's formula.

Thanks I’ll tidy it up.
Question is would you pass me? need 11 out of 18

Simpler question might be have I got 11 marks there? Not sure if I’ve scraped it

Subjotosh, would you give me any marks for my workings out?
