    Answer:

    Given:

    Length = 50 m

    Breadth = 40 m

    Height = 10 m

    Area of the four walls = {2h(l + b)} sq. unit

    = {2 10 (50 + 40)}m2

    = {20 90} m2 = 1800 m2

    Area of the ceiling = l b = (50 m 40 m) = 2000 m2

    ∴ Total area to be white washed = (1800 + 2000) m2 = 3800 m2

    Rate of white washing = Rs 20/sq. metre

    ∴ Total cost of white washing = Rs (3800 20) = Rs 76000
