Let a be the side of the square-Then according to the problem we have-a-x221A-2-20or- a-10-x221A-2-Now perimeter of the square will be 4a-40-x221A-2 cm-

Find the perimeter of a square whose one diagonal is of length is $20$ cm.

Let $a$ be the side of the square.

Then according to the problem we have,

$a \sqrt{2} = 20$

or, $a = 10 \sqrt{2}$ .

Now perimeter of the square will be $4 a = 40 \sqrt{2}$ cm.
