Answer:

Rs 1017.21

Step-by-step explanation:

                 circumference=2πr

                                 given circumference=88 m

                                therefore ,2πr=88 m

                                                    r=14 m

                             area of a circle=πr^2

                                        r=14 m

                                     therefore the area of the circle will be

                                           πr^2= 22/7*14*14

                                                     =616 m^2

    It is given that the area of this circle is equal to the area of the square garden so,

                   area of a square=l*l

                           l*l=616 m^2

                            l^2=616 m^2

                             l=√616=24.81 m

perimeter of a square=4*l

therefore the perimeter of the the square field is=4*24.81= 99.24 m

           cost of fencing one meter =Rs 10.25

 Hence the cost of fencing is= 10.25*99.24

                                          = Rs 1017.24
