That's a bit misleading.  Yes, flaps tend to increase the surface area, but
the main point is that flaps give a wing more lift.  This allows the plane
to fly slower and still stay in the air.  It also increases drag, which is
why you don't want the flaps during normal flight when you're going fast
enough.
