Question

The cost of cultivating a rectangular field at the rate of 23 per m is 13,248 if the b of the field is18m .find the cost of the field at the rate of 20per m

Answer 1

Area of the field = cost/rate = 13248/23 = 576 m²
Breadth, b = 18 m
Length, l =576/18 = 32 m
Perimeter of the field = 2(l +b) = 2(32+18) = 100 m
now, cost for fencing the field = Rs 20×100 = Rs 2000
