The total potential energy will be 55G .

Explanation:

In this question there are three systems because each mass is located at the end of each side. So,  

U1 = G m1m2/r = G(1)(2)/0.2 = 10G

U2 = G m2m3/r = G(2)(3)/0.2 = 30G

U3 = G m1m3/r = G(1)(3)/0.2 = 15G

Now the total energy will be:

U = U1 + U2 + U3

U = 10G + 30G + 15G

U = 55G
