Answer:

Step-by-step explanation:Area of the room is given by 4 * 5.5 = 22m2

Area of the verandah with room is (5.5 + 1.25 + 1.25) * (4 + 1.25 + 1.25) = 8 * 6.5 = 52

Area of only verandah = 52 - 22 = 30m2

Cost of cementing the floor of the verandah = 15 Rs/m2

Total cost of cementing 30m2 verandah = 30 * 15 = 450 Rs
