The perimeter of a square is 20cm.

Step-by-step explanation:

Given value is side of a square = 5cm,

To find:- The perimeter of a square.

Here we have to use the formula of perimeter of a square that is as follow,  

$Perimeter=4a$

Where a is side of the square.

So, the perimeter of a square is as follow,

$P=4\times side$

Substitute the value of side is 5cm we get,

$P=4\times 5\\P=20cm$

Perimeter is 20cm.

Answer 2

Answer:

Hence, value of perimeter of square will be 20 cm

Step-by-step explanation:

In context to question asked,

We have to determine the perimeter of square.

As per question,

We have,

Side of square = 5 cm

As we know that,

Perimeter of square is nothing but the addition of length of all the outer border of the square.

Perimeter of square can be determined by using formula,

$Perimeter = 4 \times Side$

So, for determining the value of perimeter of square we will put the value of side of square given in the question in above formula,

Thus we will get the value of perimeter of square as,

$Perimeter = 4 \times Side\\=>4 \times 5 \\=>20\;cm$
