**Problem Statement:**

Compute the moment of inertia of the plate of constant density \( \rho \) described by \( -a \leq x \leq a \) and \( -b \leq y \leq b \) about the x-axis. Write your answer in terms of mass, \( a \) and \( b \).

**Answer:**

\[ I = \frac{4}{3} \rho a b^3 \] 

or 

\[ \frac{m}{3} b^2 \] in terms of mass.
