Question

Find perimeter of square if diagonal is 2 underoot 2..

Answer 1

Hi ,

Let the side of the square = a

Diagonal = d = 2√2

Area of the square = d²/2

a² = d² /2

a = d / √2

a = ( 2√2 ) / √2

a = 2 units

Therefore ,

Perimeter of the square = 4a

P = 4 × 2

P = 8 units

I hope this helps you
