Question

anwer correct plz Q.10​

Answer 1

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
