The area (acres) doesn't tell the perimeter. If the 2.5 acres is square, than the perimeter is 1,320 feet. If the 2.5 acres is a field that's 100-ft wide and 1,089-ft long, then the perimeter is 2,378 feet. The perimeter can be ANY distance longer than 1,320 feet.
A 150-acre square lot has a perimeter of 10,224.68 feet.
The perimeter of a shape does not determine its area. The shape can be made thinner without changing its perimeter but reducing its area.
An area of 7 acres does not specify its shape. It can be a circular, square or in the form of an extremely long and thin strip. The first has the minimum perimeter, the latter can have an infinite perimeter.
There is no answer to that question. It depends entirely on the shape of the 300 acres.
The perimeter varies, depending on the shape.
If the three acres is a square then the perimeter would be 1,445.99 feet or 1,445 feet and 11.88 inches.
The perimeter of a 35-acre square lot is 0.935 miles.
