/sci/ - Science & Math

So /sci/ I need some problem solvers, because I'm awful at problem solving.

My girlfriend LOVES problem solving and knows I suck at it, so she made me an offer, which is this: Figure this out and she'll do ANYTHING I want, yes ANYTHING.

This is where you come in.

Here is what the rules and what not are.

A farmer is dying and he has four sons. Each son gets a house and a barn. There can be NO land wasted and each son gets a barn and a house. The area and shape MUST be the same, BUT they can be different rotations.

As I said, I'm confused, so even advice will do.
