​

Answer 1

Answer :

›»› The perimeter of the square is 36.

Given :

• Area of a square = 81 sq.

To Find :

• The perimeter of the square = ?

Solution :

Here in this question we have to find the perimeter of the square. Firstly we need to find the side of square after that we will find the perimeter of the square on the basis of conditions given above.

As we know that

→ Area = side²

→ 81 = side²

→ √81 = side

→ 9 = side

Now,

As we know that

→ Perimeter of square = 4a

→ Perimeter of square = 4 * 9

→ Perimeter of square = 36

║Hence, the perimeter of the square will be 36.║
