Okay. It's a bit long, but if you'll follow it, you'll get the answer.

You see, first you have to find the moment of inertia at one of the corners, perpendicular to the plane. I hope that would be doable.

And then, you have to use Parallel Axis Theorum. I've sent the picture above.

Hope it helps. Peace!
