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
