Answer 2

Answer:

22.63 cm (approx.)

Step-by-step explanation:

Diagonals of square divide it into two congruent right angled triangles.

So, by Pythagoras theorem,

(Diagonal)² = (Side)² + (Side)²

                  = 16² + 16²

                  = 256 + 256

                  = 512

=> Diagonal = $\sqrt{512}$

                    ≈ 22.63 cm

Therefore, diagonal of the square measures approximately 22.63 cm.
