Solution:Given; Length of the garden = 90m, Width of the garden = 75m, Width of the path around the garden = 5m
Area of rectangle = Length
×
Width
=
90
×
75
=
6750
m2
We know that, 10000 m2 = 1 hectare
Hence; 6750 m2
=
6750
÷
10000
=
0.675
hectare
Length of the garden with path

Area of the garden with path = Length

Width
=

=
9500
m
Now, Area of the path = Area of the garden with path — Area of the garden
= 9500 m2 — 6750 m2 = 2750 m2
Hence, Area of the path = 2750 m2, and area of the garden = 0.675 hectare
