Answer 2

Answer:

56

Step-by-step explanation:

Perimeter of a rectangular field   = 2(l+b)

                                                      = 2(80m+60m)

                                                      = 2 x 140m

                                                      = 280m

Distance between two poles = 5m

Therefore, total number of poles required = $\frac{280m}{5m}$

                                                                     = 56

Ans) Hence, 56 poles will be required to fence the field.
