I am not sure whether "boundary" should be used in single form or plural form. For example, should I say:
I developed this method to define A region's boundary
OR
I developed this method to define the boundaries of A region
?

"Boundary" designates the entire curve which encloses A; "boundaries" designates the several portions of that curve which respectively constitute the boundary between A and B, between A and C, between A and D, and so forth. So it seems to me the question is Which is more appropriate to your method?
