Answer:

Rs546.75

area of door=3.5*1.5=5.25sq m

area of wall=12*5.5=66sq m

area of wall to be painted=area of wall-area of door

area of wall to be painted=66-5.25=60.75sq m

total cost of painting=area of the wall to be painted*rate of painting per square meter

total cost of painting=60.75*9= Rs546.75
