What is the square perimeter of 4.5 hectares?

To find the perimeter of a square with an area of 4.5 hectares, first convert hectares to square meters: 1 hectare = 10,000 square meters, so 4.5 hectares = 45,000 square meters. The area of a square is given by the formula (A = s^2), where (s) is the side length. Thus, (s = \sqrt{45,000} \approx 212.13) meters. The perimeter (P) of a square is given by (P = 4s), which calculates to approximately (848.52) meters.
