How is the length of a river defined? ?

Is it the straight line distance from its source to its mouth? Or is it the length of the path the river actually follows?

    It is the length of the path the river actually follows, including all its meanderings.

    It is the length of the thalweg. Your job is to know what the thalweg is.
