length =20m
perimeter=100m
breadth=?
Perimeter of rectangle=2 ( l+b)
100 =2 (20 + b)
100÷2=20 + b
50=20 + b
50-20=b
I.e b=30
ans:-breadth of the rectangle is 30m

THANKS FOR THE QUESTION !

____________________________

GIVEN :

PERIMETER OF A RECTANGLE :

=> 100M

LENGTH OF THE RECTANGLE :

=> 20M

______________________________

TO FIND :

=> BREADTH OF THE RECTANGLE :

______________________________

FORMULA FOR PERIMETER OF RECTANGLE :

=> 2 ( LENGTH + BREADTH )

=> 2 ( 20 + B )

=> 40 + 2B

_____________________________

BUT PERIMETER IS GIVEN :

=> 100M

_____________________________

=> 100 = 40 + 2B

=> 2B = 100 - 40

=> 2B = 60

=> B = 60 / 2

=> B = 30

______________________________

NOTE :

=> BREADTH IS ALWAYS SHORTER THAN LENGTH .

=> SO, PLZ KINDLY CHECK THE QUESTION AGAIN

______________________________

HOPE IT WILL HELP U.......

THANKS AGAIN........
