Answer 2

$\sf Given \begin{cases} & \sf{Area\;of\;rectangle = \bf{35\;m^2}} \\ & \sf{Length\;of\;rectangle = \bf{7\;cm = 0.07\;m }} \end{cases}$

⠀⠀⠀⠀⠀⠀⠀

Need to find: Perimeter of the Rectangle?

⠀━━━━━━━━━━━━━━━━━━━━━━━━━

☯ Let Breadth of Rectangle be x cm.

⠀⠀⠀⠀⠀⠀⠀

$\dag\;{\underline{\frak{We\;know\;that,}}}$

$\star\;{\boxed{\sf{\purple{Area_{\;(rectangle)} = Length \times Breadth}}}}$

$:\implies\sf 0.07 \times x = 35$

$:\implies\sf x = \cancel{ \dfrac{35}{0.07}}$

$:\implies{\boxed{\sf{\pink{x = 500\;m}}}}\;\bigstar$

$\therefore\;{\underline{\sf{Thus,\;Breadth\;of\;rectangle\;is\; \bf{500\;m}.}}}$

⠀━━━━━━━━━━━━━━━━━━━━━━━━

Now, Finding area of rectangle,

⠀⠀⠀⠀⠀⠀⠀

$\star\;{\boxed{\sf{\purple{Perimeter_{\;(rectangle)} = 2(Length + Breadth)}}}}$

Now, We have,

⠀⠀⠀⠀⠀⠀⠀

• Length of Rectangle, l = 0.07 m
• Breadth of Rectangle, b = 500 m

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf Perimeter_{\;(rectangle)} = 2(0.07 + 500)$

$:\implies\sf Perimeter_{\;(rectangle)} = 2 \times 500.07$

$:\implies{\boxed{\sf{\pink{Perimeter= 1000.14\;m}}}}\;\bigstar$

$\therefore\;{\underline{\sf{Hence,\;The\; Perimeter\;of\;rectangle\;is\; \bf{1000.14\;m}.}}}$
