Math Riddle: Find Optimal Amount of Fence for Farmer
- hywel 12y agoJust a request that someone eventually post an answer (unless the answer is something ridiculous like blindfolding all the cows, in which case, I don't care).
- k2xl 12y agoThere's an actual answer - not a trick question!
- Red_Tarsius 12y agoAre curved fences allowed?
- k2xl 12y agoYes

- dubya 12y agoI can get it to 2.63896 down from 2.82843, assuming a unit square, but there may be a better trick.
- k2xl 12y agoCan you post the shape?
- dubya 12y agoYou can fence two adjacent sides, say north and west, and have another fence from the center to the southeast corner. That's 2+(1/sqrt(2))~2.707. The number I got was from keeping the center to SE corner fence, and finding three straight fences to join the remaining three corners. I assumed these three meet at one point and that the point is on the NW-SE diagonal.
