Area of original garden =90×75=6750 m

After path is added around rectangle, new length =90+2×5=100 m
New breadth =75+2×5=85 m
Area of rectangle with path =100×85=8500 m
2
So,
Area of path = Area of rectangle with path − Area of rectangle without path
Area of path =8500−6750
=1750 m

We know,
1 m
2
=0.0001 hectare
So,
6750 m
2
=6750×0.0001
=0.675 hectare
Hence area of ground =6750 m
2
=0.675 hectares
