MARK ME AS BRAINLIEST
Step-by-step explanation:
Area of rectangular door=length×breadth=2m×1m=2m
2
Area of wall including door=length×breadth=4.5m×3.6m=16.2m
2
Now, Area of wall excluding door
=Area of wall including door−Area of door
=16.2−2=14.2m
2
Since, The rate of white washing of 1m
2
the wall=Rs. 20
Therefore, the rate of white washing of 14.2m
2
the wall=20×14.2
=Rs. 284
Thus, the cost of white washing the wall excluding the door is Rs. 284.
