Question
A rectangular lawn 35m x 40m has two roads each 4metres
wide, running in the middle of it, one parallel to the length and the other parallel to the breadth. Find the cost of watering the lawn at the rate of Rs. 5 per square metre.Solution
Area of the first path = 35 x 4 = 140 m², Area of the second path = 40 x 4 = 160 m² and Area of centre = 4 x 4 = 16 m² Total area of both paths = 140 + 160 – 16 = 284 m² Area of the lawn with path = 35 x 40 = 1400 m² Area of the lawn without path = 1400 - 284 = 1116 m² ∴ Cost of watering = 1116 × 5 = Rs. 5580
