Answer 2

$\huge \boxed {\boxed{ \bf{Answer}}}$


$\bf \underline{given} :$


$\bf{Area \: of \: rectangle } = 504 {m}^{2}$

$\bf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 50400 {cm}^{2}$

$\bf{Length} \: = \: 42cm$

$\bf{To \: find : Breadth}$

We know ,

$\bf \underline{Area \: of \: a \: rectangle = length \times breadth.}$

=> 50400 = 42 × breadth.

=> Breadth = 50400 / 42

=> Breadth = 1, 200 cm


So, we got

$\boxed{ \bf{Breadth \: = 1200 \: cm}}$


Now,

$\bf \underline{Perimeter \: of \: the \: rectangle = \: 2(l + \: b)}$

Perimeter = 2( 1200 + 42)

= 2 (1242)

= 2484 cm.

$\boxed{ \therefore \: {\bf{Perimeter \: = \: 2484 \: cm}}}$
