Answer 1

Answer:71.4 is length

cost of fencing=11140

Step-by-step explanation:

40*l*25=71400

Answer 2

cost of cultivating per m.sq=Rs 25
cost of cultivating=71400 Rs
area=71400/25=2856 m.sq
l×b=2856
l×40=2856
l=2856/40=71.4m

cost of fencing per m=50 Rs
convert 2856m.sq into m
m=root 2856
53.45 = root 2856
cost of fencing per 53.45m = 50×53.45 =
2672.5 Rs
Cost of fencing 2856m.sq
=50×2856=142,800 Rs
