Answer 2

Given:

Find the perimeter of a square whose side is 5√2 cm​

Solution:

Know that,

The perimeter of square $\[ = 4 \times \,\,{\rm{side}}\]$

Therefore,

$\[\begin{array}{l} = 4 \times 5\sqrt 2 \\ = 20\sqrt 2 \,{\rm{cm}}\end{array}\]$

Hence, the perimeter of the square is $\[20\sqrt 2 \,{\rm{cm}}\]$.
