    i feel like the answer is pretty easy
    but i think i am being completely dumb here
    it's quadrilateral so if you have been giving the sides of AB and BC then the opposite of these sides are going to be the same and then all of the them together BUT the sides bit is throwing me out
    i can do that as well but i dunno if it's going to be right or not
    is it GCSE question and what it is out of?

    it's a gcse question and its out of 5 marks. the sides of the quadrilateral are not the same in the drawing. each one looks like a different length?
