Question

The perimeter of rectangle is 69 cm and length is 17 cm and find its breath

Answer 1

Answer:

Given :-

• Perimeter of rectangle = 69 cm
• Length = 17 cm

To Find :-

Breadth

Solution :-

${\small \mathfrak \red {\underline{ \dag \: As \: we \: know \: that}}}$

$\sf \purple{Perimeter = 2(Length + Breadth)}$

$\rm{69= 2(17 + b)}$

$\rm{69 = 34 + 2b}$

$\rm \: 69 - 34 = 2b$

$\rm \: 35 = 2b$

$\rm \: b \: = \cancel \dfrac{35}{2}$

$\mathfrak \red{ Breadth = 17.5 \: cm}$

Answer 2

Hɪɪɪ MATᴇ❀

Sᴏʟᴜᴛɪᴏɴ:

➛Perimeter = 2 (length + breadth)

➛ 69 = 2 (17 + b)

➛69= 34 + 2 b

➛69 - 34 = 2 b

➛35 = 2 b

➛BREADTH = 17 .5
