Answer 2

Hey friend, Here is your answer-

Diagonal = 7 root 2

Every angle of square is 90°

Let the length of side is x.

By using Pythagores theorem,

x^2 + x^2 = (7 root 2)^2

2x^2 = 98

x^2 = 49

x = root 7

x = 7

Therefore, the side of square is 7.

Area of square = side × side

= 7 × 7

= 49 cm^2

Hope it will help you.
