Moment of inertia of a uniform hexagonal plate about an axis \( L L \) ' is ' \( r \) ' as shown in the figure-5.117. The moment of inertia (about axis \( X X \) ) of an equilateral uniform triangular plate of thickness double that of the hexagonal plate is (Ratio of specific gravity \( \frac{\rho_{t}}{\rho_{h}}=3 \) ):
