Squares have equal side lengths, so that is why the question is only asking for one side length.
The area of a square is calculated using the formula s^2, where s stands for a side of the square.
To find the length of one side of the park, you can take the given area (3,600 m^2) and square root it. This would give you the length of one side of the square park.
√3,600 = 60
The length of one side of the park is 60 meters.
