You don't want to know the square feet of barb wahr. You only want the feet ...how far it is around the outside of the 3 acres.The answer is: It could be a lot of different things.-- The shortest possible amount of fence that can enclose 3 acres is 1,281.5 feet.That's what you need if your 3 acres is in a circle 408 feet across.-- If your 3 acres needs to have straight sides, then the shortest possible fence toenclose it is 1,446 feet. That's what you need if your 3 acres is a square, 361.5 feeton every side.-- If it's not a square, then the more rectangular it is ... long and narrow ... the morefence you need to enclose it.For just one example: If the field is 120' by 1,089', then it covers exactly 3 acres,and you need 2,418 feet of fence to enclose it.The closer to square it is, the less fence you need.
Measure the length and the height of the proposed fence. Multiply the length in feet times the height in feet for the answer: total square feet of fence fabric needed. There are also other factors to consider such as whether there will be a gate.
The maximum area possible using 100 feet of fencing is that inside a circular fence. But, since you asked about a rectangular fence: a 25x25 fence would hold 625 square feet. a 10x40 fence would hold 400 square feet. a 5x45 fence would hold 225 square feet. As you can see, the square is the rectangle that encompasses the largest area, as it is closest to a circle.
You would need 2,640 feet of fence.
225 square feet
If it is perfectly square, it will be just short of 210 feet per side. So you will need 840 feet of fence.
1 acre = 43,560 square feet. 5 acres = 217,800 square feet. That's a square 466.69 feet on a side. If you need to fence all 4 sides, then you need 1,866.76 feet of fencing.
9013 ft. square pasture
It is 77 feet long.
The only way is to increase the height of the fence.
That depends on the shape of the lot. But, assuming the lot is a perfect square, you would need 10,560 feet (two miles) of fence to surround it.
