A thin uniform rod of length 'L' and mass 'M' is bent at the middle point 'O' at an angle of 45°

A thin uniform rod of length 'L' and mass 'M' is bent at the middle point 'O' at an angle of 45° as shown in the figure. The moment of inertia of the system about an axis passing through 'O' and perpendicular to the plane of the bent rod, is [2020]
