Hii i am too in class 9

$\large \star \underline{ \underline{ \sf \: solution : }}$

$\large { \underline{ \sf \: given : }}$

• Perimeter of rectangle = Perimeter of square

• Side = 24cm

• Length = 17cm

$\\ \large { \underline{ \sf \: finding \: \: breadth : }}$

☞︎︎︎ We need to know the Perimeter.

$\\ \large \rm \: since :$

• Perimeter of rectangle = Perimeter of square

$\\ \large \sf \: perimeter \: \: of \: \: square :$

$\: \: \: \: \: \large \sf \: = 4 \times side \\ \\ \large : \implies \tt \: p = 4 \times 24 \\ \\ \large \sf \: \therefore \underline{\: p erimeter= 96cm}$

• Perimeter of square = Perimeter of rectangle

= 96cm

$\\ \large \sf \: perimeter \: \: of \: \: rectangle \\ \\ \: \: \: \: \large \sf = 2(length + breadth) \\ \\ \large \tt : \implies \: 96cm = 2(17 + b) \\ \\ \: \: \: \: \large \underline{ \sf \: on \: \: transposing \: \: terms : }\\ \\ \large \tt : \implies \: \frac{96cm}{2} = 17 + b\\ \\ \large \tt : \implies \: \frac{ \cancel{96} \: \: 48cm}{ \cancel2} = 17 + b\\ \\ \large \tt : \implies \: 48cm= 17 + b\\ \\\large \tt : \implies \: 48cm - 17cm= b$

$\large \boxed{ \underline{ \therefore\sf \: breadth = 31cm}}$
