Thread: Moment of Inertia of a Triangular plate

1. Moment of Inertia of a Triangular plate

A triangular plate has sides of lengths 2, 3 and 3, and constant mass per unit area $\rho$. Find its moment of inertia about the shorter side.

See figure attached for my attempt, I'm not quite sure what I did wrong on this one.

Can anyone spot my error?

2. Bump, still looking for a little help on this one.
