Heya

Your answer given below :

______________________________
______________________________

Solution ==>

Given that,

In a square

==> Diagonal = 13 cm

We know that,

==> Diagonal of sq. = √2 a

==> So, 13 =>√3 a

==> a = 13 / √3

==> a = 13√3 / 3 cm

Answer 2

Heya !!
We know that, diagonal of a square divides it into two equal right triangles.

Given that, diagonal of a square = 13cm

Let 'a' be the side of square.

So, By Pythagoras theorem,

H² = P² + B²

13² = a² + a² (because all sides of square are equal)

169 = 2a²

a² = 169/2

a = √169/√2

a = 13/√2
