It could be any amount greater than or equal to 1180.6 feet.
2 acres = 87120 sq feet. This has a minimum perimeter when it is in the shape of a square with sides 295.2 feet. This equals a perimeter of 4*295.2 = 1180.6 ft.
But the shape could be
290 x 300.4 requiring 1180.8 feet of Fencing, or
250 x 348.5 with perimeter of 1197.0 ft,
100 x 871.2 with perimeter of 1942.4 ft
10 x 8712 with perimeter of 17444 ft
1 x 87120 with a perimeter of 174242 ft.
The perimeter can be increased without limit by reducing one of the dimensions.
The amount of fence needed to surround 2 acres depends on the perimeter, not the area.

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)
56 posts are needed for the fence
If it is exactly 40 acres square it will take one mile of fencing or 5,280 feet. However most tracts of land are 40 acres more or less meaning they are approximately 40 acres. 40 acres is one quarter mile long on each side more or less.
60 acres is 9013 ft. in square pasture
The amount of fence needed to surround 2 acres depends on the perimeter, not the area.
9013 ft. square pasture
Any measure greater than or equal to 1181 feet - up to infinitely many feet.
If the area is a square then a minimum of 1,104.4 feet of fencing would be needed.

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 depends on the shape of the lot. But, if the lot was a perfect square, you would need 2,891.98 feet of fence to surround it.
56 posts are needed for the fence
That would depend on the length and width of the acreage.
