#### Solution

Length (l) of garden = 90 m

Breadth (b) of garden = 75 m

Area of garden = l × b = 90 × 75 = 6750 m^{2}

From the figure, it can be observed that the new length and breadth of the garden, when path is also included, are 100m and 85m respectively.

Area of the garden including the path = 100 × 85 = 8500 m^{2}

Area of path = Area of the garden including the path − Area of garden

= 8500 − 6750 = 1750 m^{2}

1 hectare = 10000 m^{2}

Therefore, area of garden in hectare = 6750/10000 = 0.675 hectare
