The cost of ploughing a square field at ₹13.50 per square metre is ₹5400. Find the cost of fencing the field at ₹28.50 per metre.

Answer 1

Cost of ploughing square field = Rs 5400

cost of ploughing 1 m^2 field = 13.50

area of ploughing = 5400/13.50 = 400m^2

area of square field = side^2

400 = side^2

side of square = 20m

perimeter of square field = 4×side = 4×20 = 80m

cost of fencing 1 m = Rs 28.50
