NUMERIC RESPONSE
(16) We do not need the exact formula for the moment of inertia of a triangular plate about one of its sides to find the answer to this question.
If the side length of the triangle is a and the mass of the triangle is 
, then the moment of inertia will be proportional to 
.
Now, the mass 
will itself be proportional to 
(because the mass will proportional to the area of the triangle)
So, the moment of inertia is proportional to
