Answer:  (3) Rs. 20160

Solution:-
The length and width of a rectangular wall = 30 meters and 24 meters

Then, area of rectangular wall = 30 x 24
= 720 m^2

The rate of painting is Rs.28 per square metre.
Therefore, cost of painting of wall = 720 x 28
= Rs. 20160

Hence, the correct answer is option (3) Rs. 20160.
