Answer:
653.7143 m2
Step-by-step explanation:
Area of circular park= 22/7 x 17 x 17
=6359/7
=908.2857 m2
Radius of inner circle = radius of park - width of path
=17-8
= 9m
area of inner circle = 22/7 x 9 x 9
= 1782/7
= 254.5714 m2
area of path = area of park - area of inner circle
= 908.2857 - 254.5714
= 653.7143 m2
