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
