1. Step-by-step explanation:

   Perimeter = 2(50+30) = 2(80) = 160m

   Thus total cost = 160 × 60 × 3 = Rs.28800

2. Answer:

   • The total cost of the wire needed for the fence is Rs 28800.

   Step-by-step explanation:

   Given that:

   Dimensions of a rectangular plot,

   • Length = 50 m
   • Breadth = 30 m

   To Find:

   • What will be the total cost of the wire needed for the fence?

   Finding the perimeter of the rectangular plot:

   We know that.

   Perimeter = 2(Length + Breadth)

   ⟶ Perimeter = 2(50 + 30)

   ⟶ Perimeter = 2 × 80

   ⟶ Perimeter = 160

   ∴ Perimeter of the rectangular plot = 160 m

   Finding the total length of wire:

   A triple fence has to be put along its edges.

   • Total length to be fenced = 3 × 160 m
   • Total length to be fenced = 480 m

   ∴ Total length of wire = 480 m

   Finding the total cost of wire:

   The wire costs 60 rupees per metre.

   • 1 m of wire costs = Rs 60
   • 480 m of wire costs = Rs (60 × 480)
   • 480 m of wire costs = Rs 28800

   ∴ The total cost of the wire needed for the fence = Rs 28800
