here is your answer
let the length be 3x, breadth be 2x
now,
area=3x*2x
3456=6x square
3456/6=x squer
576root=x
24=x
so, length =3*24=72
breadth=2*24=48
now,
perimeter=2*(l+b)
=2*(72+48)
=2*120
240
now,
cost of fencing=240*4=₹960
hope this will help you

Let length be 3x
Breadth be 2x
Area of rectangular feild = L X B
3456 =(3x)X(2X)
3456 =6Xsquare
3456/6 = X square
576 = X square
Under root 576 = X
24 = X
Length=3x24=72
Breadth=24x2=48
Perimeter of rec =2(72+48)=240
Cost of fencing =240x4=960
