d. Cannot be determined
e. None​

Answer 1

Answer: option B is the correct answer i.e. 400 meters

Step-by-step explanation: let length be =3x meters

breadth =2x meters

ATQ

3x = 2x + 40

3x- 2x = 40

x = 40

length = 3x = 120meters

breadth = 2x = 80meters

perimeter = 2[120 + 80]

2[ 200]

= 400 meters
