Hii i am too in class 9
[tex] \large \star \underline{ \underline{ \sf \: solution : }} \\ [/tex]
[tex] \large { \underline{ \sf \: given : }} \\ [/tex]
[tex] \\ \large { \underline{ \sf \: finding \: \: breadth : }} \\ [/tex]
☞︎︎︎ We need to know the Perimeter.
[tex] \\ \large \rm \: since : \\ [/tex]
[tex] \\ \large \sf \: perimeter \: \: of \: \: square : \\ [/tex]
[tex] \: \: \: \: \: \large \sf \: = 4 \times side \\ \\ \large : \implies \tt \: p = 4 \times 24 \\ \\ \large \sf \: \therefore \underline{\: p erimeter= 96cm} \\ [/tex]
= 96cm
[tex] \\ \large \sf \: perimeter \: \: of \: \: rectangle \\ \\ \: \: \: \: \large \sf = 2(length + breadth) \\ \\ \large \tt : \implies \: 96cm = 2(17 + b) \\ \\ \: \: \: \: \large \underline{ \sf \: on \: \: transposing \: \: terms : }\\ \\ \large \tt : \implies \: \frac{96cm}{2} = 17 + b\\ \\ \large \tt : \implies \: \frac{ \cancel{96} \: \: 48cm}{ \cancel2} = 17 + b\\ \\ \large \tt : \implies \: 48cm= 17 + b\\ \\\large \tt : \implies \: 48cm - 17cm= b\\ \\[/tex]
[tex] \large \boxed{ \underline{ \therefore\sf \: breadth = 31cm}}[/tex]
