Explanation-:
Let s be the length of aside of a square .
Given ,
Perimeter of a square-:36 cm = 4s
= 4s = 36 cm
= s = 36/4
= s= 9
To find ,
As we know that ,
Diagonal of a square (d) -: √2s
∴d= √2 x 9
= d = 9 √2
= 12.73
12.73 cm is a length of diagonal of a
square.

Some other formula for square -:
Perimeter = a+ a + a + a , a= length of
side of square
Area = s x s , s = length of side of a
square
Diagonal of a square (d) -: √2s. ,
d= diagonal
S= length of side of a square
