please note that work W done by stretch your spring will be storage by that spring as potential energy, so:
$$W=\frac{ 1 }{ 2 }k \Delta ^{2}$$
where k is spring constant and Delta is the displacement.
So inserting your numerical data, you will get:
$$W=\frac{ 1 }{ 2 }*9.1*(0.139)^{2}=0.0879Joules$$
