Verified Answer
The circular grass lawn of radius35mhas a path of width7maround it on ...

r = 35 m; R = 35+7=42 m
Area of circular path 
= π(R+r)(R−r)
= 22/7(42+35)(42−35) = 1694m2

Given:
Radius of circular grass lawn = 35m
Width of the path around the lawn = 7m

To find: Area of the path

Solution:
We can find the area of the path by subtracting the area of the circular grass lawn from the area of the larger circle that includes the path.

Area of circular grass lawn = πr^2
= π(35)^2
= 3850π

Radius of larger circle = radius of circular grass lawn + width of the path
= 35 + 7
= 42m

Area of larger circle = πr^2
= π(42)^2
= 1764π

Area of the path = Area of larger circle - Area of circular grass lawn
= 1764π - 3850π
= 1914π
≈ 6010.4m²

Therefore, the area of the path is approximately 6010.4m², which is closest to option D) 1694m².

Hence, option D is the correct answer.
