let the side of square is a

so

a^2 = 144

a = 12

hence perimeter = 4*a

=4 * 12

= 48 cm

Answer 2

GivEn:

• Area of square = 144cm²

To finD:

• Perimeter of square

Solution:

Here, we have given that area of square is 144cm².

As We know :

Area of square = side²

So, we can say that 144cm² is equal to side² of square.

Let solving this :

Area of square = side²

⇒ 144 = side²

⇒ Side = √144

⇒ Side = 12

⛬ side of square is 12cm.

Here,

we found that side of square is 12cm.

Hence, using formula of perimeter of square :

Formula using:

Perimeter of square = 4 × side

Substituting values in formula:

Perimeter of square = 4 × side

⇒ Perimeter of square = 4 × 12

⇒ Perimeter of square = 48

⛬ Perimeter of square = 48cm

Our final required answer:

$\large{\sf{◉ Perimeter ~of~ square~ = 48cm.}}$
