Max value of the average normal stress in the links.

Homework Statement

Here is the problem along with the solution:

I am confused about part (a). Why is it that the area used is 2*0.008*(0.036-0.016). If you draw a cross section at just one of the holes, wouldn't that give you the max average stress? So the area used should instead be 0.008*(0.036-0.016)?

Never mind, figured it out! For those who are interested, there are actually two links not one!
