Answer:
Dimensions of veranda
Length = 2.25 + 5 + 2.25 = 9.5m
Breadth = 2.25 + 3 + 2.25 = 7.5 m
1. Area of verandah including room = 9.5 X 7.5 = 71.25 m^2
2. Area of room = 5x 3 = 15 m^2
Therefore, area of verandah = 1. - 2.
= 56.25 m^2
Cost of cementing 1m^2 = Rs.275
Therefore, cost of cementing verandah = 56.25 × 275
= Rs.15468.75
