Answer:
₹201.5625
Step-by-step explanation:
Given :- Lenght of room = 5.5m
Width of room = 4m
Verandah's width = 1.25m
Rate of cementing = ₹15/m²
To find :- Area of verandah and cost of cementing it.
Solution :- Area of room = 5.5m × 4m
= 22m²
[Lenght of room + verandah = 5.5m + 1.25m
Width of room + verandah = 4m + 1.25m]
Area of room + verandah = 6.75m × 5.25m
= 35.4375m²
Area of verandah = 35.4375m² - 22m²
= 13.4375m²
Cost of cementing the verandah = 13.4375m² × 15
= ₹201.5625
