Question

A room is 6.2 m long, 3.8 m wide and 3.2 m high.It has 3 doors each 2m x 1.2m and 2 windows each 1.2m x 1.5m.Find the cost of white-washing its walls at the rate of Rs 10 per square metre.

Answer 1

Answer:

area of 2 doors = 2×2×1.2 = 4.8m^2

area of 2windows = 2×1.2×1.5=3.6 m^2

area of four walls = 2(l+b)h

=2(6.2+3.8)×3.2

=64m^2

area for white washing= 64 - (4.8+3.6)

=55.6m^2

cost = 55.6×10 =556 rs
