The perimeter of the rectangular park is calculated as 2 x (length + breadth) = 2 x (150 + 120) = 2 x 270 = 540 m. Fencing costs 40 rupees per metre. Multiply the total perimeter by the cost per metre to find the total cost: 540 x 40 = 21600 rupees. This method ensures accurate cost estimation for fencing any rectangular area.
