Question

if the diagonal of a square is 13 cm then find its side​

Answer 1

Answer:

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

Step-by-step explanation:

Remember the relation between diagonal and side of a square.

Diagonal of a square =√2 × Side of a square

Means,

$side = \frac{diagonal}{ \sqrt{2} }$

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

We can simplify further by rationalising the denominator.

$side = \frac{13 \sqrt{2} }{ \sqrt{2} \times \sqrt{2} }$

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