Question

If a diagonal of a square is $13cm$ then find its side

Answer 1

The diagonal of thee square is given as $13cm$.

Let $a$ be the side of the square.

$Diagonal=13$

$\sqrt{2}a=13$

$a=\frac{13}{\sqrt{2}}$

$a=\frac{13\sqrt{2}}{2}$

$a=6.5\sqrt{2}cm$

Therefore, the side of the square is $6.5\sqrt{2}cm$.
