Are smooth surfaces embedded in R3 , with bounded area, always the boundary of a finite perimeter set?

Take a smooth surface S in R3 embedded , with finite area. Can we say that the "interior" A of S is a Borel set? If yes, one can use the Gauss-Green Theorem to say that A has finite perimeter.

For example the sphere S^2 in R3 can be seen as the boundary of the open ball in R3; and so one can think of the ball as a finite perimeter set.

The bound on the area is fundamental, the embedded property assure that one can't have some issues with intersections; I don't know if there is some problem with the orientability.
