how can you make a fence with the least amount of materials that encloses maximum possible area? this one is bit " curved " and needs to think outside the " Fence "

Please type your subject in the School Subject box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.

We don't usually make "curved fences".
Mathematically, with a limited length of fence, a fence in the form of a circle encloses the maximum area.
If the fence has to be straight, then it's a square has the maximum area for a given length of fence (or the least fence for the same area).
