Answer 2

${ \underline{\underline{ \red{ \bf{Your \: Question:}}}}}$

 A wire of length 30cm is bent to form a rectangle of length 12cm, find the breadth of rectangle.

${ \underline{\underline{ \green{ \bf{Required \: answer:}}}}}$

${ \underline{\underline{ \pink{ \bf{Given:}}}}}$

Length of the wire=30cm

${ \underline{\underline{ \blue{ \bf{We \: can \: get:}}}}}$

So, perimeter of the rectangle=30cm

Length of the rectangle = 12cm

${ \underline{\underline{ \blue{ \bf{To \: find:}}}}}$

Breadth = ?

${ \underline{\underline{ \blue{ \bf{Solution:}}}}}$

As,

Perimeter = 2(l+b)

30 = 2 (12+B)

30 = 24 + 2B

30 - 24 = 2B

6 = 2B

B = 3

${ \underline{\underline{ \blue{ \bf{Therefore:}}}}}$

Breadth = 3 cm Ans
