Answer:

Length of rectangle = 11 m

Step-by-step explanation:

Perimeter of rectangle = 2(l + b)

Breadth (b) of rectangle = 9 m

To find Length (l) of rectangle

According to question ,

Perimeter of rectangle = 40 m

= 2(l + b) = 40

= 2(l + b) = 2(20)

= l + b = 20

= l + 9 = 20

= l = 20 - 9

= l = 11

Therefore , length of rectangle = 11 m
