INR 495
Step-by-step explanation:
The total area of wall = Length x Breadth
= 5 x 7
= 35 sq. m
Area of window = 1.5 x 2
= 3 sq. m
Area left for painting the wall = total area of wall - aea of window
= 35- 3
= 33 sq. m
cost of painting the wall = 15 per sq. m
the total cost of painting = 33 x 15
= INR 495
