Let π be a commutative ring with identity and π(π) be the set of ideals with non-zero annihilator. The strongly annihilating-ideal graph of π is defined as the graph SAG(π) with the vertex set π (π)* = π (π) \{0} and two distinct vertices I and J are adjacent if and only if I β© Ann(J) β (0) and J β© Ann(I) β (0). In this paper, we study the metric dimension of SAG(π) and some metric dimension formulae for strongly annihilating-ideal graphs are given.
