How to calculate LCB and VCB using simpson's rule

Dear all,

Am a student and i need your help on a calculation. i was given a line plan with a SIB, i was told to find the LCB & VCB of the vessel using this line plan.

Firstly, how can i determine the ordinates from the line plan? the drawing was made on A4 Sheet, and I try to bring out the drawing from the plan but i dont know how to get the value for each ordinates

secondly, i was asked to use atleast 3 ordinates for the calculation, but when i brought out the 1/2 ordinates, i discover only two of them have the same common interval

please i need a breakdown formular to calculate this LCB and VCB and how to determine the ordinate value.
