Step-by-step explanation:

Dimensions of the hall as given are = length x breadth x Height = 20×15× 10

Total cost = cost per sq. meter * Surface area of the walls in sq. m

                = 60(LH + BH + LH+ BH) = 60 (2LH + 2BH)

                = 60*2*H(L + B) = 120 * H(L + B)

                = 120 * 10 * (20 + 15) = 1200*35 = 42000

Therefore, total cost is  ₹42000.00
