Answer 2

Answer:

Let the side of square be of length a unit.

As sides are perpendicular to each other, by Pythagoras theorem can be applied for the value of diagonal.

→ side² + side² = diagonal²

→ a² + a² = ( 10√2 )²

→ 2a² = 200

→ a² = 100

→ a = 10

Hence,

→Perimeter of square = 4 * side

→ 4 * 10

→ 40
