उत्तर
Length (l) of garden = 90 m
Breadth (b) of garden = 75 m
Area of garden = l × b = 90 × 75 = 6750 m2
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 m2
Area of path = Area of the garden including the path − Area of garden
= 8500 − 6750 = 1750 m2
1 hectare = 10000 m2
Therefore, area of garden in hectare = 6750/10000 = 0.675 hectare
