123. The Farmer, Four Sons and Oil Drills

Easy Medium Hard Extreme

A farmer discovers oil on his farm. He decides to live on the area marked "A", exactly in the middle of the farm. How should he divide the rest of the farm equally between his four sons so that:
(1) all 4 farms have the same shape,
(2) there is 1 oil drill on each of the 4 farms,
(3) he has each son as a neighbor?

Can you achieve this by just adding 8 sticks to the existing layout?
