Answer:
rectangular grassy lawn measuring 40 m by 25 m is to be surrounded externally by a path which is 2 m wide . Calculate the cost of leveling the path at the rate of Rs 8.25 per square meter . Let PQRS be the rectangular grassy lawn and let length = AB Given Length PQ 40 m and breadth QR = 25 m Area of lawn PORS = 40m 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 I am Rate of levelling the path = Rs . 8.25 per m² Cost of levelling the path = ( 8.25 x 276 ) = Rs . 2277 Solution : Now , Area of the path = Area of ABCD - Area of the lawn PQRS = 1276 m² 1000 m² 276 m² RD Mensuration - 1 ( 2. One meter wide path built inside a square park f side 30 m along its sides . The remaining part of the park is covered by grass . If the total cost of covering by grass is Rs 1176 , find the rate per square metre at which the park is covered by the grass . U'S ne Learn and breadth = 80 PAGE NO
