Answer:

The additional grassy ground shall it graze is 1208.9m^{2}

Step-by-step explanation:

the rope was initially 12 m long then the area will be graze =\pi r^{2}

                                                                                              = \pi (12^{2})

                                                                                              = 3.14*144

                                                                                              =452.16

the rope then extend to 23 m from 12 m long then the area will be graze =\pi r^{2}

                                                                                              = \pi (23^{2})

                                                                                              = 3.14*529

                                                                                              =1661.06

so the additional area covered will be = extended area -initial area

                                                                = 1661.06 - 452.16

                                                                    =1208.9m^{2}
