Since your property is a square if the length of a side is x feet then x^{2} = 152460 and thus x = √152460 = 390.46 feet. Thus once around the four sides of your property is 4 × 390.46 = 1561.85 feet. Since there are 5280 feet in a mile to walk 1 mile you need to walk around the property 5280/1561.85 = 3.38 times.
