Rectangular field

perimeter = 2(l+b) i.e. 2(200+150) 2×350= 700m

ii). cost of fencing 1m= Rs 50
cost of fencing 700m = 700×50 35000 Rs
iii). area of rectangle = l×b
= 200×150= 30000m^2

cost of ploughing per sq m = rs 8
cost of ploughing 30000sq m = 30000×8 = 240000 rs

A) Perimeter of Rectangle = 2(l+b) = 2(200+150) = 700m
b) Cost of fixing fence for 1m = Rs 50
     Cost of fixing fence for 700m = 700*50m
                                     = 35,000 Rs.
c) Area of Rectangle = l*b = 200*150
                                   = 30,000m²
d) Cost of ploughing 1m² = Rs 8 per square meter
   Cost of ploughing 30,000m² = 30,000*8
                                                 = 2,40,000 Rs
