CORRECT ANSWER IS

Answer 2

ANSWER

Length of rectangular garden=90m and breadth of rectangular garden=75m

Outer length of rectangular garden with path=90+5+5=100m

Outer breadth of rectangular garden with path =75+5+5=85m

Outer area of rectangular garden with path=length×breadth=100×85=8,500m2

Inner area of garden without path=length×breadth=90×75=6,750m2

Now, Area of path=Area of garden with path−Area of garden without path

=8,500−6,750

=1,750m2

Since, 1m2

= 1/10000 hectares

Therefore, 6,750m2 = 6750/10000

=0.675 hectares.

I hope it will help.

Please consider the 2 after each m as metre square.
