Answer:
rs 450(Approximate)
Step-by-step explanation:
Area of the room without vrandha = 5.5×4 = 22.0m²
length of the room with vrandha = (5.5+1.25+1.25)= 7m
width of the room with vrandha =(4+1.25+1.25) = 6.5m
So area of the room with vrandha = 8×6.5 = 52m²
Therfore area of vrandha = area of the room with vrandha - area of the room
= (52-22) = 30m²
Now cost of cementing the floor of vrandha = 30×15 = rs 450
