Step-by-step explanation:
Given, Length of room = 5.5m, Width of room = 4m, Width of verandah which is constructed all along outside of room = 1.25m, Cost of cementing of verandha = Rs 15 per m²
Therefore, Length of room with verandah = 5.5m + 1.25m + 1.25m = 8m Width of room with verandah = 4m +1.25m + 1.25m = 6.5m
Area of room = Length x width
= 5.5m x 4m = 22.0 m²
Area of room with verandah = Length x Width
=8m x 6.5m = 52m²
Area of verandah = Area of room with verandah – Area of room = 52m² –22m² = 30 m²
Cost of cementing of verandah = Area x Rate
Rs 15 x 30m²=Rs 450
