Answer:28 cm

Step-by-step explanation:Area given=392 sq cm

Area of square = side × side

side×side=392

side=

Now we got the length of the side.

square makes 90 degree angles

Therefore, By using Pythagoras Theorem,

Length of the diagonal will be 28 cm

Let a be the side of a square

## . Then area = a^2 = 392.

When the side = a, the diagonal = a rt2. Therefore, diagonal squared = 2a^2 = 2(392) since a^2 = 392.

✍Hence, diagonal = 2(14)=28.

⟹ 28 is the answer
