I assume (?) you want to eat as many cheez-it's as possible.

 

In that case, the width of the first is $\frac{22}{2}-9=2$, and the width of the second is $\frac{20}{2}-5=5$.

 

So it's a $9\times 2$ rectangle and a $5\times 5$ rectangle. Which has greater area? (In other words, which of $9\times 2$ and $5\times 5$ is larger)
