Thank you for the opportunity to help you with your question!
a) here, moment of inertia =
(2.9+2.1+4.3+2.5)*3^2 = 106.2 kgm^2
because each mass is 3 m from the x axis
b) now we consider distances from the y axis; each mass is 2m from the y axis:
c) the distance from the rotation axis is now found from the pythagorean theorem
