How many fence post for 11 acres at 10 feet apart?

Answer 1

Specifying the area inside the fence doesn't tell you the shape or the distance

around it (the "perimeter"). Here are the shortest possibilities. It could be

anything longer than these.

-- The shortest possible perimeter, requiring the least fence, is to enclose

the area inside a circle. For 11 acres, the diameter of the circle has to be

781 feet, and the distance around it is 2,453.8 feet ... that's 246 fence

posts, not including whatever you do for a gate.

-- If the sides of the lot are straight, then the shortest possible perimeter

is a square. For 11 acres, each side of the square has to be 692.2 feet, and

the distance around it is 2,768.8 feet ... that's 277 fence posts plus the gate.

If the lot is rectangular and not square, then the longer and skinnier it is,

the more fence it'll need, with no limit. For example, the lot could be 33-ft

wide and 14,520-ft long. That's 11 acres inside, and 29,106-ft around ...

2,911 fence posts plus the gate.
