Question

1. Find the perimeter of a square of side 3 cm.​

Answer 1

Answer:

Side of square =3 cm

Perimeter of square =4×side

=4×3 cm

=12 cm

Perimeter of square is 12 cm.

Answer 2

Answer:

Hence the perimeter of the square is $12$ cm.

Step-by-step explanation:

As per the data given in the above question,

Given that:-

The side of a square is $3$ 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 = $3$ cm,

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

$P = 4 \times 3$

Multiplying $4$ by $3$, we get

$P = 12 cm$  

Hence the perimeter of the square is $12$ cm.
