Answer:
first find area of wall
then find area of window
subtract area of window from area of wall
Step-by-step explanation:
length of window = 3m
width of window = 2m
area of window = 3 x 5
= 15
length of wall = 6m
width of wall = 5m
area of wall = 6 x 5
= 30
area to white wash = 30 - 15
= 15
cost of 1 m2 = 25
cost of white washing wall = 25 x 15
= 325
