Question

A rectangle perimeter is 13 cm and it's breath is 11/3 cm what's its length.

​

Answer 1

$\huge{ \fbox{ \red{Answer}}} \\ \\ \\ \\ { \fbox{ \purple {Given}}} \\ \\ \\ perimeter \: of \: the \: rectangle = x \\ \implies 13cm \\ \\ breadth \: of \: the \: rectangle = y \\ \implies \frac{11}{3} cm \\ \\ \\ { \fbox{ \purple{To \: find}}} \\ \\ \\ length \: of \: the \: rectangle\:(l). \\ \\ \\ { \fbox{ \purple{Solution}}} \\ \\ \\ We \: know\: that: \\ \\ \implies perimeter of a rectangle=2(length+breadth) \implies\:x=2(l+y) \implies 13 = 2(l+{\frac{11}{3}})$

Answer 2

ᴀɴꜱᴡᴇʀ :->

ɡίѵεη →

$perimeter \: of \: the \: rectangle \: = \: x \\ \\ = > \: 13cm$

$length \: of \: the \: rectangle \: = y \\ \\ \frac{11}{3} cm$

TO ᖴIᑎᗪ :-

$length \: of \: the \: rectangle \: (l).$

ꜱᴏʟᴜᴛɪᴏɴ :-

$we \: know \: that$

$= > perimeter \: of \: a \: rectangle \: = 2(length \: + breadth) \: \\ \\ = > x = 2(l \: + \: y) \\ \\ 13 = 2(l + \frac{11}{3} )$

=> 13= 2ʟ+ 11/2

=> 13-11/2 = 2ʟ

=> 15/2 = 2ʟ

=> ʟ= 15/2*2

=> ʟ = 15/4 ᴄᴍ
