Answers
Answer:
Step-by-step explanation:
The area in which white washing will be done= area of wall - area of door.
Area of wall = 4.5m×3.6m.
= 16.2m².
Area of door = 2m×1m.
= 2m².
Area of white washing = 16.2m²- 2m².
= 14.2m².
Cost of white washing = area of white washing × cost per sq.m.
= 14.2×20.
= Rs.284.

Answer:
Step-by-step explanation:
Length of the door =2m
Breadth of the door =1m
Area of the door =l x b
=2 x 1
= 2m Square
Length of the wall = 4.5 m
Breadth of the wall = 3.6 m
Area of the wall = l x b
= 4.5 x 3.6
Area of the wall = 16.2 m Square
Area of the wall to be white washed = 16.2 - 2
= 14.2 m Square
Cost of white washing per m Square= 20 rupees
Cost of white washing per 14.2 m Square =?
14.2× 20
= 284 rupees.
