area of field = 71400/30
= 2380 m sq.
l×b= 2380
l×40=2380
l=2380/40
l=59.5 m
perimeter of the field=2(l+b)
=2(59.5+40)
=2×99.5
=1990m
cost of fencing=50×1990
=₹99500
= 2380 m sq.
l×b= 2380
l×40=2380
l=2380/40

wrong answer kjennifer write is 51m,rs9100
how it can be possible bcz if we multiply l×b (51×40) then its not equal to the area obtained!!!
