Question

find the breadth of a rectangular whose perimeter is 360 cm and whose length is 140 cm
​

Answer 1

Answer:

40

Step-by-step explanation:

Perimeter of a rectangle = 2( l+b )

=> 360 = 2( 140+b )

=> 360 = 280 + 2b

=> 360 - 280 = 2b

=> 80 = 2b

=> 80/2 = b

=> 40 = b

Therefore, the breadth is 40 cm.

Answer 2

Answer:

$\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: { \large{ \underline{ \frak{ \pink{Answer}}}}} :$

Perimeter= 2(l+b)

360= 2( 140+ b)

180= 140+ b

180- 140= b

40cm= breadth.
