Question

if the area of square is 729sq.m then its perimeter is ?

Answer 1

Answer:

$Area \: of \: Square \: = 729 \: {m}^{2}$

$Side \times Side \: = 729$

$Side \: = \sqrt{729}$

$Side = 27 \: m$

$Perimeter \: = 4 \times Side$

$= 4 \times 27$

$= 108 \: m$

Answer 2

Answer:

Let the side of square be x m.

$area \: of \: squqre \: = 729 \: {m}^{2} \\ \\ {x}^{2} = 729 \\ \\ x = \sqrt{729} \\ \\ x = 27 \: m$

Now

Perimeter of square = 4x

= 4 × 27

= 108 m

Hope it helps.
