SIR u have given the diagram and written the numbers (which i found out signify areas and then solved it) in the triangle… it could also mean that they are length of sides bo , oc and bc
is ther any convention we need to know….
No convention Girish, probably I should have centred the numbers better but my drawing skills are a litlle wonky 😀 The original question I saw also just gave this info and I didn’t have any difficulty identifying what was meant. However it was remiss of me; I have now edited it to make it clearer.
