Answer 2

A N S W E R

$\begin{gathered}\frak{Given}\begin{cases} \textsf{ \: \: \: Area \: of \: the \: rectangular \: plot} = \frak{440 {m}^{2} }&\\ \\ \textsf{ \: \: \: Length \: of \: the \: rectangular \: plot} = \frak{22m}\end{cases}\end{gathered}$

_________________________________

We know that,

Area of the rectangle = Length × Breadth

$:\implies\sf{440=22×Breadth}$

$:\implies\sf{Breadth=440/22}$

$:\implies{\boxed{\frak{\pink{Breadth=20m}}}}$

Then,

Perimeter of the rectangle = 2(l + b)

$:\implies\sf{2(22+20)}$

$:\implies\sf{2(42)}$

$:\implies{\boxed{\frak{\pink{84m}}}}$

${\underline{\textsf{Hence,Perimeter~ of~ the~ rectangle~ plot~ is~ {\textbf{84 m.}}}}}$
