Answer:
Let the length of the square be x.
then A/q
perimeter will be (18 + x) cm (1)
Now, by formula of perimeter of square =4*(length of its side)
= perimeter is 4 x X=4x (2)
But from (1),we have perimeter = 18 + x
So, 18 + x = 4x
= 18 = 4x-x
=18 = 3x
=> 3x = 18
=>x =18/3
=>x = 6 cm
Length of its side is 6 cm
Got it?
