By using this formula,

P = 4 √ A

  • Substitute the value in the formula
  • P = 4 √400
  • P = 4 × 20
  • P = 80cm

So the perimeter of square is 80cm.

  • The perimeter of Square is 80 cm.

Step-by-step explanation:

Given:-

  • Area of square = 400cm²

To Find:-

  • It's Perimeter

Formula used:-

  • Area of Square = (Side)²

  • Perimeter of Square = 4 × Side

Solution:-

Area \:of\: Square\: =\: (Side)²

400\: =\: (Side)²

Side\: =\: \sqrt{400}

{\boxed{\red{Side\: =\: 20\:cm}}}

Now,

Perimeter \:of\: Square\: = \:4×Side

Perimeter \:of\: Square\: = \:4×20

{\boxed{\red{Perimeter \:of\: Square\: = \:80\:cm}}}

Hence, The Perimeter of given Square is 80 cm.
