Best answer

Length of rectangular garden = 90 m and breadth of rectangular garden = 75 m

Outer length of rectangular garden with path

= 90 + 5 + 5 = 100 m

= 75 + 5 + 5 = 85 m 

Outer area of rectangular garden with path

= length x breadth = 100 x 85 = 8,500 m2 

Inner area of garden without path = length x breadth 

= 90 x 75 = 6,750 m2 

Now Area of path = Area of garden with path – Area of garden without path

= 8,500 – 6,750

= 1,750 m2

Since, 1 m2 =1/10000 hectares

Therefore, 6,750 m2 = 6750

= 0.675 hectares
