If you will say the correct answer I will mark you as brain list. ​

Answer 1

Answer:

1320 Rs

Step-by-step explanation:

Since the gardener makes 2 rounds of the fence

Thus,

length of rope required=2×circumfrece of the circular garden

diameter=42m

radius=diameter/2

radius=42/2=21m

Circumference of the circular grden=2πr

=2×22/7×21

=2×22×3

=44×3

=132

length of rope required=2×circumference of the circular garden

=2*132=164 m

cost of rope for 1 m=5 Rs

cost of 264 m=264×5

=1320 Rs

Answer 2

diameter=42m

therefore,radius=diameter/2=42/2=21m

circumference of the garden=length of the fence =2πr=2×22/7×21m=132m

length of 2 round of fence=132×2m=264m

per meter it costed 5 ruppes

264 meter it costed 264×5 ruppes

=1320 ruppes
