Question

of a diagonal of a square whose side is 6cm​

Answer 1

$\mathfrak{\huge\underline{Answer:}}$

Method 1:

If square is split into two from diagonal then it forms two right angled triangles which are congruent.

Therefore we can use Pythagoras theorem as we know side

d^2=6^2+6^2

d=√72

d=6√2

d=8.485m

Method 2:

Using formula

d=s√2

d=6√2

d=8.485m

You can find length of diagonal of any square if you know the length of side using formula.

d=s√2

Where s is length of side

Hope this helps..
