Step-by-step explanation:

Answer 2

Answer:

Given that is

The length of side of a square is 8cm

Then diagnol = ?

So ,

$In \: triangle ABD$

${ab}^{2} + {ad}^{2} = {bd}^{2}$

${8}^{2} + {8}^{2} = {bd}^{2}$

$2 + {8}^{2} = {bd}^{2}$

$bd = \sqrt[8]{2}$

Step-by-step explanation:

So the diagnol is

$\sqrt[8]{2}$
