    I'm stuck on question 10a) doing kruskals algorithm, here is the question:

    For my working out I have done

    I have the wrong order and the wrong length,
    the correct order is
    GF, BD, EG, DC, HJ, AD, GF, CF
    With total length as 31

    I have no idea where I have gone wrong, the answer hasn't included I for some reason too and used GF twice so i'm confused

    I see nothing wrong with your answer.

    Where you have a choice of edges of the same weight, the order can vary. CD then EG, or EG then CD; both are correct.

    Regarding the "correct" answer:
    There are 10 nodes and so a spanning tree must have 9 edges.
    You cannot get a repeated edge.
    It must include "I".
