    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.
