Question

Find the area of varanda 2.25cm wide constructed outside the room 5.5m long and 4m wide​

Answer 1

Answer:

Given: Length of room =5.5m,

Width of room =4m,

Width of verandah which is constructed all along outside of room =2.25m,

Cost of cementing of verandha = Rs 200 per sq.m

∴, Length of room with verandah=5.5+2.25+2.25=10m

Width of room with verandah=4+2.25+2.25=8.5m

Area of room=Length×Width=5.5×4=22m ²

Area of room with verandah= Length×Width=10×8.5=85m²

Area of verandah=Area of room with verandah−Area of room=85−22=63m ²

Cost of cementing of verandah=Area×Rate=63×Rs.200=Rs.12600
