Answer:
(a) 21 m
(b) 7 m
Step-by-step explanation:
11.
(a) Given Area of circular grass lawn = 1386 m².
Radius of the grass lawn = √Area/π
= √1386/22/7
= √441
= 21 m.
Hence, 1078 = Area including the path - 1386
Area including the path = 1386 + 1078
= 2464 m²
Radius of circular grass lawn + Path
= √2464/π
= √2464/22/7
= √784
= 28 m
Therefore, Width of the path = 28 - 21
= 7 m.
Hope it helps!
