A while ago i participated in the national Australian mathematics competition there was a question which had me well and truly stumped and in extra attempts outside the paper continued to stump me any help would be appreciated, thanks.
AB = 11cm
BE : EG : GH = 1 : 2 : 3 (ratio)
CF : FH = 4: 5 (ratio) (independent of the previous ratio)
Find the length of AD
