                         Tahap Menarik Kesimpulan


                        Berdasarkan kegiatan tersebut apa yang dapat ananda simpulkan?



                                               Keliling jajar genjang adalah  ...............................................
                                                ..............................................................................................
                                                ..............................................................................................

                                               Sehingga diperoleh rumus keliling jajar genjang:


                                               K = …+…+…+…

                                               Dan luas jajar genjang adalah ...............................................

                                                ..............................................................................................
                                                ..............................................................................................

                                               Sehingga diperoleh rumus luas jajar genjang:

                                               L =
