Answer 2

Answer:

The perimeter of the square is $80$ cm.

Step-by-step explanation:

As per the data given in the above question,

Given that:-

The side of a square is $20$ cm,

We have to find the perimeter of a square,

Here we have to use the formula of the perimeter of a square,

i.e., $P = 4 a$

Where a is the side of the square,

Given a = $20$ cm,

Substitute the value of side in the above formula of the perimeter of the square we get,

$P = 4\times 20$  

Multiplying $4$ by $20$, we get  

$P = 80 cm$  

Hence the perimeter of the square is $80$ cm.
