Answer:
880 m^2
Step-by-step explanation:
Diameter of flower bed = 66m
Radius = 33 m
Area of flower bed = (22/7) * r^2
= (22/7)*33^2
Radius of flower bed and path = 33 + 4 = 37 m
Area of flower bed + path = (22/7) * 37^2
Area of path = Area of flower bed + path - Area of flower bed
= (22/7) * (37^2 - 33^2) [a^2 - b^2 = (a+b) (a-b)]
= 880 cm^2
