Step-by-step explanation:
Given,
breadth of the wall = 3.6 m
length of the wall = 4.5 m
breadth of the door = 1.5 m
length of the door = 2 m
cost of whitewashing per m^2 = ₹20
Now,
Area of the wall = length (L) × breadth (B)
= 4.5 × 3.6
= 15.75 m^2
Area of the door = length (L) × breadth (B)
= 2 × 1.5
= 3m^2
Therefore Area of wall without the door = 12.75 m^2
Cost of whitewashing the wall = 12.75 × 20
= ₹255
Cost of whitewashing the wall is ₹255
