Answer:
Rs. 528.
Step-by-step explanation:
Diameter of the circular garden=21m
∴ Radius of the circular garden=[tex]21/2 m[/tex]
Now, circumference of circular garden=2πr=2×[tex]22/7[/tex]×[tex]21/2[/tex]
=22×3=66m
The gardener makes 2 rounds of fence so the total length of the rope of fencing =2×2πr=2×66=132m
Since the cost of 1 meter rope=Rs. 4
Therefore, cost of 132 meter rope=4× 132=Rs. 528.
