Solution

Area of the room is given by 7.5m×5m = 37.5m2
Area of the verandah with room is given by (7.5+1.25+1.25)m×(5+1.25+1.25)m=10m×7.5m=75m2
The area of the verandah = 75m2 - 37.5m2 = 37.5m2
Cost of cementing the floor of the verandah = Rs.15/m2
Total cost of cementing the floor of the verandah = 37.5×15=Rs562.5
