I think it will help you make me branlist have a nice day

Step-by-step explanation:

Area of original garden =90×75=6750 m

2

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

2

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
