Hopefully I can enlighten you with my knowledge.

First, the corral is 160 = A.

Not sure if you know this, but any rectangle with a given area has a minimized perimeter when all its dimensions are the same (so a square). Square root 160 and you get:

12.64

This means that the side length of the corral will be 12.64 all around. Now since we divide the corral into for equal retangles, we divide 12.64 by 4 to get:

3.16.

This means that each small rectangle will be 12.64 by 3.16.
