Please answer with detail explanation

(b) Four identical particles of mass 2.50 kg each are placed at the vertices of a 4.0 m x 2.0 m
rectangle and held there by four massless rods, which form the sides of rectangle. What is the
rotational inertia of this rigid body about an axis that (i) passes through the midpoints of opposite
sides and lies in the plane of the rectangle, (ii) passes through the midpoint of one of the sides and
is perpendicular to the plane of the rectangle and (iii) lies in the plane of the rectangle and passes
through two diagonally opposite particles?
