Given :

• Length of the rectangular plot = 0.3 km = 300 m
• Breadth of the rectangular plot = 0.4 km = 400 m .
• Cost of wire = ₹ 10/metre

To find :

• Cost of wire required for fencing.

Solution :

★ Perimeter of the plot:-

• 2(l + b)

→ 2(300 + 400)

→ 2 × 7000

→ 14000 m

★ For 5 rows length of wire:-

→ 14000 × 5

→ 70000

★ Cost of the wire required for fencing:-

→ 70000 × 10

→ ₹700000

Answer :

• The cost of the wire required for fencing is ₹700000
