Answers
Answer:
426 rupees
Step-by-step explanation:
area of wall = l*b
= 4.5 * 3.6
= 16.2m^2
area of door = l*b
= 2*1
= 2m^2
area of wall need to be painted excluding door = 16.2m^2 - 2m^2
= 14.2m^2
cost of white washing per m^2 = 30 rupees
14.2m^2 = 14.2 * 30
= 426 rupees
Answer:
426 rupees
Step-by-step explanation:
area of wall = l*b
= 4.5 * 3.6
= 16.2m^2
area of door = l*b
= 2*1
= 2m^2
area of wall need to be painted excluding door = 16.2m^2 - 2m^2
= 14.2m^2
cost of white washing per m^2 = 30 rupees
14.2m^2 = 14.2 * 30
= 426 rupees
