48 sq.cm

Step-by-step explanation:

Answer 2

Given:

• Area of square board = 144 m²

To Find:

• Perimeter of square board.

Concept Knowledge:

Here, we have to find Perimeter. We are given with the area. Area of square is (side²). So by using formula we will solve. Then as we will get the side we will use tye perimeter formula and find our answer.

Solution:

Let the side of square be 'x'.

⇨ Area of square = side²

⇨ 144 = x²

⇨ √144 = x

⇨ 12 = x

So, the value of the side is 12m.

According to Question:

We have to find Perimeter.

⇨ Perimeter of square = 4 × sides

⇨ Perimeter of square = 4 × 12

⇨ Perimeter of square = 48m

Final answer:

So, the perimeter of square is 48cm.

Hence, option (a) is correct.
