Step-by-step explanation:

perimeter of rectangle = 2(l+b)

                                      2(50+30)

                                      2(80)

                                      160 cms

Cost of per m = ₹50

160 cms in meters = 160/100

                                1.6 m

cost = 1.6*50

          ₹80
