The area of a square is the side of the square squared or A= s^2 (s meaning side of the square)
Perimeter or the 4 sides is P= 4 x s
Since the area is 6561, plug that into the area formula so you get 6561= s^2
Next, take the square root of both sides of the equation because that is the opposite of squaring a number)
When you do that you get s = 81
Now that you know s, plug it into the Perimeter formula P= 4 x 81
The perimeter or distance around the park is 324 meters.
