The amount of fence needed to surround 2 acres depends on the perimeter, not the area.
9013 ft. square pasture
The maximum area that you can enclose with 3000 feet of fencing would be a circle of radius 477.46 feet. This circle would have an area of 716197.2 square feet which is 16.442 acres. The minimum area that you can enclose is infinitesimally small - go for a very, very long and very, very narrow area.
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.
An acre is 66 feet by 660 feet so 1,452 feet of fence would surround an acre.
An area 696 feet by 500 feet would encompass approximately 8 acres.
60 acres is 9013 ft. in square pasture
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.
That would depend on the length and width of the acreage.
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.
If the area is square-shaped, you would need 2,425 feet of fencing.
If the area is a square then a minimum of 1,104.4 feet of fencing would be needed.
9013 ft. square pasture
Any measure greater than or equal to 1181 feet - up to infinitely many feet.
That all depends on the shape of the lot. But, if the lot was a perfect square, you would need 5,280 feet (one mile) of fence to surround 40 acres.
That would be 8.26 acres.
About 15.5 acres.
There are 43, 560 square feet in an acre. There are 348,480 square feet in eight acres. Assuming that the area is a square, you will approximately need 2361.28 feet of fencing. If the area is one foot wide, you will need a lot more fence than that.
