Solution:
We have been given,Radius (r) = 7cm.
Radius (R) = 35cm.
The radius of bigger circle (with the path) is a circular grass lawn + Path running around the grass lawn.
Substituting the values,
Area of the path Area of bigger circle Area of smaller circle
Substituting the values,
Thus, the area is 1694 m2.
Hence, option 3 is correct.
