Answer 1

QUESTION:

➡Find the length of the diagonal of a square with sides 8cm.

ANSWER:

➡As we know each angle of a square is 90°

And each side is 8cm(given)

We can use pythagoras theorem

Let diagonal be x,

x²=8²+8²

x²=64+64

x²=128

x=8 √2.

So, length of the diagonal of the square is

x=8 √2.
