How to do this sum ?
​

Answer 1

Step-by-step explanation:

Length of diagonal = 50cm

so x+x= 50+50 because we have taken x value as 50 such as the diagonal so now we will add it and then the answer will be 50+50= 100

Answer 2

Answer:100$\sqrt{2}$

Step-by-step explanation:

$\sqrt{2}$x=50

or, x=50/$\sqrt{2}$=25$\sqrt{2}$

Now, the perimeter of a square = 4x=4*25$\sqrt{2}$=100$\sqrt{2}$
