Question

A room 9.5 m long and 6 m wide is surrounded by a 1.25-m-wide verandah. Calculate the
cost of cementing the floor of this verandah at 80 per m
6. ​

Answer 1

Room length =9.5 m
Room breadth= 6m
Then, verandah length =9.5+ 1.25= 10.75 m
Verandah height = 6+1.25= 7.25 m
Area of verandah= (10.75*7.25)- ( 9.5*6) = 77.9375- 57 = 20.9375 m
Cost of cementing= 20.9375*80= 1,675 rupees....
