Answer 2

Answer:

Hello Finex!

Let the radius of park be x

Now circumference of park is

$2\pi r \\ \\ = 2 \times \frac{22}{7} \times r = 616 \\ \\ r = \frac{616 \times 7}{44} \\ \\ = 98m$

Now radius of park =98m with 14m wide path

Radius of park excluding path=(98-14m)=84m

Area of park excluding path

$= \frac{22}{7} \times 84 \times 84 \\ \\ = {22176m}^{2}$

Total cost of grossing

$= 22176 \times 1.40 \\ \\ = rs \: 31046.40$

Hence required area is 22176m^2

Total grossing coat= Rs 31046.40
