area of room=5.5×4=22.0m^2
area of room + verandah= (5.5+2.25+2.25)×(4+2.25+2.25) = 85m^2
therefore area of verandah only = 85-22= 63
and cost of cementing the floor = 63×200=12600
area of room + verandah= (5.5+2.25+2.25)×(4+2.25+2.25) = 85m^2
therefore area of verandah only = 85-22= 63
and cost of cementing the floor = 63×200=12600
