Hey there!
Let's solve this problem step by step!
Since we're dealing with a square, the lengths off all sides are the same.
We can find the length of one side by dividing the total circumference by 4 (the number of sides of a square).
Length of one side = 360 meters / 4
Length of one side = 90 meters
The formula to find the area of a square is multiplying a side by another side (multiply length by width, but because they are the exact same, you can just pick one side and plug it in twice).
Area = length × width
Area = 90 × 90
Area = 8100 square meters.
Hence, the answer is 8100 m^2.
