Circumference of circular field = 

we are given that the circumference of circular filed is 88 m

So, 

We are given that A circular path of width 2 m runs around the circular field

So, outer radius R = 14+2 = 16 m

The area of the circular path=Outer area - inner area

                                              =

                                              =

                                              =

Cost of tiling 1 sq.m. = Rs.39

Cost of tiling 188.57 sq.m. = 

Hence the cost of tiling the path at the rate of rs. 39 per m square is Rs.7354.23
