Question

The perimeter of a rectangular sheet is 100cm.If the length is 35cm, find the breadth and the area

Answer 1

Answer:

Here is ur answer.

30 cm

Step-by-step explanation:

Let the breadth be X.

Perimeter = 2(Length + Breadth)

100 cm = 2( 35 cm + X)

100 cm = 70 cm + X

X = 100 cm - 70 cm

X = 30 cm

So, Breadth = 30 cm

Hope this will help you.

Answer 2

$\huge \mathtt {\underline{Answer}}$

$\large \underline{\pink {\underline {\red{\frak{Given::}}}}}$

$\sf \mapsto{Perimeter \: of \: rectangle=100cm}$

$\sf \mapsto{Length \: of \: rectangle = 35cm}$

$\large \underline{\pink {\underline {\red{\frak{To \: find::}}}}}$

$\sf \rightarrow{Breadth \: of \: rectangle. }$

$\sf \rightarrow{Area \: of \: rectangle. }$

$\large \underline{\pink {\underline {\red{\frak{Formula \: r equired::}}}}}$

$\boxed{ \bf{Perimeter \: of \: rectangle = 2(length + breadth)}}$

$\boxed {\bf{Area \: of \: rectangle = length \times breadth}}$

$\large \underline{\pink {\underline {\red{\frak{According \: to \: Question::}}}}}$

${ \implies{ \sf{Perimeter \: of \: rectangle = 2(length + breadth)}}}$

$\sf {\implies{100cm = 2(35 + breadth)}}$

$\sf{ \implies{ \frac{100}{2}cm = 35cm + breadth }}$

$\sf{ \implies{ 50cm = 35cm + breadth }}$

$\sf{ \implies{ breadth = 50cm - 35cm = 15cm}}$

$\pink \star{\boxed {\bf{Breadth \: of \: rectangle \: is \: 15cm.}}} \pink \star$

${ \implies{\sf{Area \: of \: rectangle = length \times breadth}}}$

${ \implies{\sf{Area \: of \: rectangle = (35\times 15) {cm}^{2} }}}$

${ \implies{\sf{Area \: of \: rectangle = 525{cm}^{2} }}}$

$\pink \star{\boxed {\bf{Area\: of \: rectangle \: is \: 525 {cm}^{2} .}}} \pink \star$
