Understand the geometry of a square and its diagonal.

When a diagonal divides a square, it forms two right-angled triangles. The two sides of the square ($s$) act as the legs of the right triangle, and the diagonal ($d$) acts as the hypotenuse.

According to the Pythagorean theorem, for a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

To find the length of one side ($s$), we can rearrange the equation:

The problem statement is incomplete as it does not provide the length of the diagonal ($d$). Without this value, a numerical answer for the side length cannot be determined.

If you can provide the length of the diagonal, I can help you calculate the side length and round it as requested! Send me the next one 📸
