Question

Find the perimeter of a square of area. 289cm²​

Answer 1

Given :

Area : 289 cm²

Area = a²

a = √area

a = √ 289

a = 17

Now ,

perimeter = 4 × side

Perimeter = 4 × 17

Perimeter = 68 cm

Hope it helps ❣️

Answer 2

Step-by-step explanation:

Given that,

Area of the square = 289 cm²

Let the side of the square be x

Since, Area = side ²

=> 289 = x²

=> 17*17 = x²

=> 17² = x²

[when power are equal the bases are also equal]

=> x = 17

Therefore, Side of the square = 17 cm

Now, Perimeter = 4* side

= 4* 17

= 68 cm.

Therefore, Perimeter of the square is 68 cm.
