Answer 2

Answer:

Rs.4950

let

D=24m

R=D/2

∴R= 24/2 =12

Now:

If the width of the path inside the park= 3m

Then:

Radius of the inside circle = R-W

∴R=12-3=9

Area of the path = pi R^2 - pi r^2

A=pi(R+r) (R-r)

=pi(R+r)

=(22/7) (12+9) (3)

=22*3*3

∴A=198m^2

Cost of paving per square metre=Rs.25

∴Cost of paving total area of the park =25*198

=Rs. 4950
