Let PQRS be the rectangular grassy lawn and let length = AB and breadth = BC Given Length AB = 40 m and breadth BC = 25 m Area of lawn PQRS = 40 m x 25 m = 1000 m2 Length AB = (40 + 2 + 2) m = 44 m Breadth BC = (25 + 2 + 2) m = 29 m Area of ABCD = 44 m x 29 m = 1276 m2 Now, Area of the path = Area of ABCD – Area of the lawn PQRS = 1276 m2 – 1000 m2 = 276 m2 Rate of levelling the path = Rs. 8.25 per m2 Cost of levelling the path = (8.25 x 276) = Rs. 2277
