Given :

  • A fish tank is of the shape of a square of side 160 m

To find :

  • Perimeter of the fish tank
  • Cost to put a barbed wire around it at the rate of Rs. 11.50

Knowledge required :-

→ Formula to calculate perimeter of square :-

  • Perimeter of square = 4a

where, a denotes the side of the square.

Solution :

Periemter of the fish tank :-

→ Perimeter = 4a

→ Perimeter = 4 × 160

→ Perimeter = 640

Perimeter of the fish tank = 640 m

→ Cost to put a barbed wire around 1 m of the fish tank = Rs. 11.50

→ Cost to put a barbed wire around 640 m of the fish tank = 11.50 × 640 = 7360

Cost to put a barbed wire around the fish tank = Rs. 7360
