Length of the door = 2 m
Breadth of the door = 1 m
{tex}\therefore{/tex} Area of the door = l {tex}\times{/tex} b
= 2 {tex}\times{/tex} 1
= 2 m2
Length of the wall = 10 m
The breadth of the wall = 4 m
{tex}\therefore{/tex} Area of the wall = l {tex}\times{/tex} b
= 10 {tex}\times{/tex} 4
= 40 m2
{tex}\therefore{/tex} Area of the wall excluding door
= 40 m2 – 2 m2 = 38 m2
{tex}\therefore{/tex} Cost of white washing the wall = Rs. 38 {tex}\times{/tex} 120
= Rs. 4560
Hence, the cost of white washing the wall is Rs. 4560
