Answer:

2529.92 sq cm

Step-by-step explanation:

Area of the rectangular cardboard = l x b

                                                          = 145×32

                                                          = 4,640 sq.cm

Area of the the Circular Plates = πr²

                                                   = 3.14×4²

                                                   = 2,110.08 sq.cm

Area of the remaining portion of the

cardboard sheet                                 = Area of the Cardboard - Area of the

                                                                     Circular plates

                                                            = 4,640 - 2,110.08

                                                            = 2,529.92 sq.cm

Therefore, the Area of the remaining portion of the Cardboard sheet is

                                                   2,529.92
