Hence the area of the border is 580 sq.cm.

Answer 2

Answer:= 580 cm

Step-by-step explanation:

area of border = total area - area of photograph

so area of photograph = 35*22 cm

                                      = 770 cm

total area  = 45*30 cm

                  = 1350 cm

area of border = 1350 - 770 cm

                        = 580 cm
