since total area of lawn is 45*25=1125

when one round is comleted,

 area covered by cutter in one round=(45*25)-(21*41)

                               =1125-861=264

area covered by cutter another half round=(19*2)+(41*2)

                                                        =38+82=120

therefore total area covered by person=264+120=384
