Answer:

1584m^2

Step-by-step explanation:

area covered in 1 revolution = 2 x 22 x 60 x 84/7

                                               = 44 x 720

                                               = 31680cm^2

area covered in 500 revs = 500 x 31680

                                           = 15840000cm^2

                                           = 1584m^2
