You can put this solution on YOUR website! The area of the square equals side squared, s^2. Therefore, a side equals to the square root of the area: That's the length of each side, 9.
If we trace a diagonal across the square, we are in fact dividing the square into 2 triangles, and the diagonal line is the hypotenuse.
Per Pythagoras:
The length of the hypotenuse equals the square root of the sum of the squares of the sides:
12.73 is the length of the diagonal
