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
