Answer:

10cm

Step-by-step explanation:

Let's divide the square into two right angled triangle.

As the sides of triangles are equal and taking the diagonal as hypotenuse .

Apply the pythaghoras theorem ; that is  A²+B²=C²

Taking side of square x,

⇒x²+x²=(10√2)²

⇒2x²=100×2

⇒2x²=200

⇒x²=100

⇒x=10cm
