Distance covered = 7*5*perimeter

side a = 80 m
side b = 50 m

perimeter = 2(a+b) 
                 = 2(80+50) = 2*130 = 260 m

distance covered = 35*260 = 9100 m
                
9100/1000 = 9.1 kilometer

Rectangle : Area=l*b
                        =80*50
                        =4000sq.m
Area covered in a week=5*4000*7=140000sq.m
Distance covered=140000/50=2800m
                        =2800/1000
                        =2.8km.
