Total cost of fencing the park shown in Figure is Rs. 55000. Find the cost of fencing per metre.

Answer:

Total perimeter for fencing the park = FE + ED + DC + CB + BG + GF \[=280\text{ }cm+270\,\,cm+180\text{ }cm+120\text{ }cm\]                                     \[=1100\,\,m\]                                                                                                                                        But it is given, the total cost of fencing the park = Rs. 55000. \[\therefore \] Cost of fencing the park for 1100 m = Rs.  55000 \[\therefore \] Cost of fencing the park for per metre                         \[=\frac{Rs.\,\,55000}{1100}=Rs.\,\,50\]                                                                                                  Hence, the cost of fencing per metre is Rs. 50.
