The lateral area of a rectangular prism is 156 square inches. What are the possible whole-number dimensions of the prism if the height is 13 inches?

Since lateral area = (perimeter)(height), would it be something like...

$\displaystyle 156 $$\displaystyle =$ $\displaystyle (a)$$\displaystyle (13)$

...? And if that were how you set it up, how would I split $\displaystyle a$ up to be those four sides of the base of the prism?

I just can't seem to wrap my head around it
