The length of the whole area = 20 + 20 = 40 m

The breadth of the whole area = 30 + 20 = 50 m

New area of the ground with the path = 40 × 50 = 2000 m2

Cost of lighting the whole ground along with the path = 2000 × 120 = 240000

∴ The cost of lighting the whole ground along with the path is Rs. 240000.
