Calculate I x I x and I 0 I 0 for the rectangle in Exercise 31 assuming

Calculate $I_x$ and $I_0$ for the rectangle in Exercise 31 assuming a mass density of $\delta (x,y)=x$.

Data From Exercise 31

Let R be the rectangle [−a, a] × [b, −b] with uniform density and total mass M. Calculate:
The mass density δ of R
I_x and I₀
The radius of gyration about the x-axis
