Displacement from Bonjean's

Hi guys..need some giudance....i was going through the topic bonjean curves...i have worked out how to find the transverse area in about 20 stations of the ship...now i need to find displacement from these values..i went through Princi: of naval archi: and ship stability for master and mates: but still cant understand....the vessel im doin the calculations on is a bulker of abt 200 m with unevenly spaced 20 stations....can somebody tell me how to find displacement from transverse areas in SIMPLE TERMS ?..thanks a lot.....

Have a look at the attached image.

Draw the given W.L.
Find the intersection of the W.L. & each station
Find the immersed area of each station
Use numerical integration to find the disp. and C.B.
