Hint: For answering this question we will analyse the definition of perimeter and derive the formula for the perimeter of a square that is four times of the length of a side of a square and use it and find the perimeter of the square given in this case.

Complete step by step answer:
Now considering from the question we have the side of the square is $9cm$ .

The definition for perimeter of any object is the total length of the boundaries of the object.
In the case of a square it has four equal boundaries known as sides so we can say that its perimeter is the sum of the lengths of the four sides which will be equal to four times of the side of the square which is mathematically given as $4s$ .
Here we have a square with the length of the side $9cm$ , we need its perimeter that is four times of the given side length mathematically it is equal to $4\times 9cm$ .

By simplifying this we will have the perimeter of the square is $36cm$.

Note: While answering questions of this type we should be careful while performing the calculations. It would be better if we are aware of the formulae of perimeters and areas of different shapes for rectangle the perimeter is $2\left( l+b \right)$ and the area is given by $lb$ and for triangle the area is given by $\dfrac{1}{2}bh$ and the area of square is ${{s}^{2}}$ .
