Answer: Area of Square = 81m^2
Explanation:
To find the area of a square you just need to know the side length on one side, and since we know that the perimeter is 36, and all sides of a square are equal we can divide 36/4, to get 9 is your side length.
Now to actually find the area you can just square your side length, so basically 9x9, which gives you 81, your answer!!
