The area is not sufficient information to determine the length and width. First of all, there is no reason to suppose that the area is rectangular as opposed to circular or triangular or some other simple or complicated shape. Even if, on the basis that the question asks for length and width, you assume that it is a rectangle, there are infinitely many possible answers: ranging from a nearly square area to an extremely long, very thin strip.
Well, first you need to know the length of barbed wire in a roll. Then you need to know the perimeter of the fence (in feet or metres) you are going to build around that 180 acres. Then, calculate it this way: (length of barbed wire in one roll) x (perimeter of fence of 180 acres) = (total length of wire needed for "n" ft. (or m) of fence perimeter of one strand) (total length of wire needed for "n" ft.(or m) fence perimeter of one strand) x 5 = (Grand total length of wire needed to fence 180 acres) (Grand total length of wire needed to fence 180 acres) / (length of barbed wire in one roll) = (# of rolls needed for a five-strand barbed wire fence for 180 acres)
60 acres is 9013 ft. in square pasture
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.
160post at 20 ft. apart
80 acres is 880 x 440 feet. Depends on how many cattle and how rough they are on your post settings. Most people around here in Oklahoma put their t-posts roughly 16' apart. This will take 164 posts. A roll of barbed wire will usually run a quarter of a mile of fence. So on a typical 5 wire fence it will take 30 rolls of barbed wire.
9013 ft. square pasture

It depends on what kind of animal you are trying to fence in (or out). For an average cattle pasture, I prefer setting them 10 feet apart, so you would need about 150 T-posts. I still prefer setting three six-inch treated wooden posts for each corner; they will hold up better to the tensioning of the fence/barb wire.
1, if the roll is large enough!
320 Acres = 1 294 994 sq/msq rt of 1 294 994 = 1137.98 (one side)1137.98 x 4 = 4551.91m of 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.
That would depend on the length and width of the acreage.
