Find the cost levelling a playground 51m long and 40m wide at Rs. 35 per square meter . find also the cost of fencing it at Rs. 45 per meter .

Answer»

Area of ground = length *breadth = 51*40 = 2040 m^2Perimeter of ground = 2(length + breadth) = 2(51+40) = 2*91 = 182 mCost of levelling ground= 2040*35 = Rs 71400

Cost of fencing = 182*45 = Rs 8190
