It may seem that your topic is specific and focused so capable of a fairly simple factual answer.
In fact flaps and slats are an important PART of an aircraft design and as such are affected by other parts so the simple facts about them will probably only be 90% of the story the last 10% involving many other factors of the aircraft.
Whenever you are thinking about any aircraft (or feature of that aircraft) you must constantly tell yourself that all flying is about two things:
Lift (and having enough to cope with the weight)
Control (if you cannot easily and reliably control both the amount of lift and the direction it is acting you do not have a safe aircraft)
Your topic involves mainly the provision of lift but also will affect control (especially when flying close to or in a stall)
As a SIMPLE example of the constant interaction of all the factors of an aircraft's design consider that if you are running out of ideas about how to get more lift you could tackle your problem by using a lighter structure and reducing weight. Similarly if your aircraft is not strong enough you may have to increase weight which will mean you have to find more lift.
