Area of a square field is 169 sq. m. Find its perimeter

$\: \huge\colorbox{pink}{Answer}$

Area of square field

$= 169sq. \: m$

∴ side × side = 169 sq. m

$\: ⇒side \: \times side$

$= (13 \times 13)sq. \: m$

$\: ⇒ \: \: \: \: \: side \: = 13 \: m$

Side of the square is 13 m.

Perimeter of the square field

$\: = 4 \times side$

$= (4 \times 13)m \: = 52m.$

Hence, perimeter of the square field is 52 m.
