Question

If there of a square is 49 cm2 then its perimeter is :​

Answer 1

Answer:

side of the square = a

Area of a square = axa=49cm²

                             a²=49

                             a= √49= 7

perimeter of a square = 4a = 4 x 7 = 28

Answer 2

• Perimeter of square is 28 cm.

Step-by-step explanation:

Correct Question:-

• If area of a square is 49 cm². then its perimeter is

_____________________________

Given:-

• Area of square is 49 cm².

To find:-

• Perimeter of square.

Solution:-

• We need side for Perimeter. So,

We know that,

Area of square = Side × Side

So,

➝ 49 = (Side)²

➝ √49 = Side

➝ 7 = Side

Or, Side = 7

Perimeter of square = 4×side

= 4 × 7

= 28

Therefore,

Perimeter of square is 28 cm.
