Area of a rectangular field is 1200 m^2.
let length 3x and width x
thus,3x×x=1200
3x^2=1200
x^2=400
x=20
so,3x=3×20=60m
x=20m
perimeter=2(60+20)m
=160m

Answer:
Step-by-step explanation:
length = l
breadth = b
lb = 1200
l = 3b (given)
3b * b = 1200
b*b = 1200/3
b*b = 400
b = sqrt.400
b = 20
perimeter = 2(l+b)
l = 3b
l = 3 * 20 = 60
perimetre = 2(60+20)
perimetre = 2(80) = 160m
