I understand the actual knob on a breast for a feeding purpose . Wouldn’t just that be enough ? Why the areola around it especially with a different shade of colour to the rest of the breast ?

While what people are saying is true in terms of how helpful they are for things like baby feeding, baby seeing them better, etc.
That’s not how genetics work. A trait just needs to be passed on. Even if it is an absolutely horrible trait. Case in point, a lot of birds are brightly colored. Thus helps them attract a mate, but it gets them killed because they know longer camouflaged and actually stick out.
The actual reason we have areolas is because someone of our distant ancestors were born with them and were successful in mating and transferring it down. Considering there were at least a dozen different humanoids at one point. There could have been one species that didn’t have areolas. And they could have been superior in just about every way. Homosapiens nearly went extinct and was believed to be in the thousands at one point. Again it’s not that areolas were better or had a great purpose (I mean they could have. Everyone has already pointed to the benefits) it was just passed down through the surviving humans.
