⠀⠀⠀⠀

• Breadth = ??

$\sf{\bold{\green{\underline{\underline{Solution}}}}}$

⠀⠀⠀⠀

$\sf{\red{\boxed{\bold{perimeter = 2 ( length + breadth ) }}}}$

⠀⠀⠀⠀

$\sf :\implies\: {\bold{ 110 = 2 ( 35 + breadth )}}$

⠀⠀⠀⠀

$\sf :\implies\: {\bold{ \dfrac{110}{2} = ( 35 + breadth )}}$

⠀⠀

$\sf :\implies\: {\bold{ 55 = ( 35 + breadth )}}$

⠀⠀⠀⠀

$\sf :\implies\: {\bold{ breadth = 55- 35 }}$

⠀⠀⠀

$\sf :\implies\: {\bold{ breadth = 20cm }}$

• Required breadth = 20cm

Answer 2

Answer:

✯ Given :-

• The perimeter of a rectangle is 110 cm and its length is 35 cm.

✯ To Find :-

• What is the breadth of the rectangle.

✯ Formula Used :-

$\boxed{\bold{\large{✮\: Perimeter\: =\: 2(l\: +\: b)\: ✮}}}$

✯ Solution :-

$\sf Given \begin{cases} & \sf{Perimeter = \bf{110\;cm}} \\ & \sf{Length (l) = \bf{35\;cm}} \end{cases}$

➙ According to the question,

➣ 2(l + b) = 110

➣ 2(35 + b) = 110

➣ 35 + b = $\sf\dfrac{\cancel{110}}{\cancel{2}}$

➣ 35 + b = 55

➣ b = 55 - 35

➠ b = 20 cm

$\therefore$ The breadth of the rectangle is 20 cm .
