A rectangular lawn measures 75 meters by 55 meters and is surrounded by a 2.5-meter-wide path on all sides outside the lawn. Calculate the area of this path and the total cost to build it if the construction rate is Rs. 2 per square meter.

Explanation

The total area including the path is calculated by increasing both length and width by twice the width of the path: (75 + 2*2.5) * (55 + 2*2.5) = 80 * 60 = 4800 sq. m. The original lawn area is 75 * 55 = 4125 sq. m. The path area is the difference: 4800 - 4125 = 675 sq. m. At Rs. 2 per sq. m, the cost is 675 * 2 = Rs. 1350.
