Moment of inertia of a point mass, located a distance, r, from the axis of rotation is

$\overline{){\mathbf{I}}{\mathbf{=}}{\mathbf{m}}{{\mathbf{r}}}^{{\mathbf{2}}}}$

The location of mass A from the axis of rotation is determined using the Pythagoras theorem. Distance, r, is equal to the height of the triangle.

Find the moment of inertia about an axis that passes through masses B and C.

Express your answer to two significant figures and include the appropriate units.
