A garden is 90 m long and 75 m broad. A path 5 m wide is to be built outside and around it. Find the area of the path. Also find the area of the garden in hectares.

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
Outer breadth of rectangular garden with path = 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, 1m² = 1/10000 hectares
Therefore, 6,750 m² = 6750/10000 = 0.675 hectares
