Given: Length of the rectangular field=110 m

Breadth of the rectangular field=85 m

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

=2(110+85)=2×195

Perimeter of the rectangular field=390 m

Cost to fence the field per metre=Rs.25

Cost to fence the field 390 metre=Rs.25×390=Rs.9,750‬

∴ Cost of fencing the field =Rs.9750
