What is the perimeter of 5 acres?

An acre is 43560 square feet, imagine a square:

208.7103

X 208.7103 ft.

The perimeter of ONE acre (adding all 4 sides) would be

208.7103

+208.7103

+208.7103

+208.7103

= 834.8413 feet.

The perimeter of FIVE acres (five of these sqares side by side or 208.7103 X 1043.5516) would be:

208.7103

+ 1043.5516

+ 208.7103

+ 1043.5516

= 2504.5239

There are 5820 feet in a mile, so the perimeter of 5 acres is 0.474 miles

The above answer is only true if the area is in the form of a 5*1 rectangle. Was there any justification for selecting that configuration?
