Answer 1

Answer:

Rs. 13410

Step-by-step explanation:

Area of walls = 2h(l+b)

                        2*4.5 (5.2+3)

                        73.8 m^2

Area of ceiling = lb

                           5.2*3

                           15.6 m^2

Total area = 73.8+15.6

                     89.4 m^2

Cost = 89.4 * 150

           ₹ 13410
