A quarter section (160 acres) is half a mile on each side.
How the length is worked out
1 acre = 43,560 ft². A square of A acres has sides of √(A × 43,560) ft and a perimeter four times that. A rectangle or odd shape needs more fence for the same area; a circle needs the least.
Example: a square 160-acre plot needs 10,560 ft of fence (3,219 m): 8 rolls of barbed wire per strand or 32 rolls of field fence.
