Answer:
Step-by-step explanation:Area of field=71400/35 =2040 sq. m
LxB=area
Lx40=2040
L=2040/40=51
Length=51m
Perimeter=2(l+b) =2(51+40) =2x91 =182m
Cost of fencing field@50 per metre=182x50 = ₹9100 (Ans.)

Step-by-step explanation:
given
cost of cultivating a rectangular field = rupees 35/m ^2
there fore area of rectangular field which is cultivated for rupees 71400 = 71400 / 35 = 2,040 m^2
area = lb
lb = 2,040m^2
l*40 = 2,040
l 2,040/20 = 51m^2
the length of field = 51m^2
fencing of field = perimeter of rectangle
2 (l+ b) = 2 (40+51) = 182m^2
cost of fencing = rupees 50/m^2
total cost = 182*50 = rupees 9,100
