Answer:
2750
Step-by-step explanation:
Solution:Given; Length of the garden = 90m, Width of the garden = 75m, Width of the path around the garden = 5m
Area of rectangle = Length `xx` Width
×
Width
=
90
×
75
=
6750
m
We know that, 10000 m2 = 1 hectare
Hence; 6750 m2 `= 6750 ÷ 10000 = 0.675` hectare
=
6750
÷
10000
=
0.675
hectare
Length of the garden with path `= 90 m + 5m + 5m = 100 m`
=
90
m

m

Width of the garden with path `= 75 m + 5m + 5m = 95 m`
=
75

m
=
95
m
Area of the garden with path = Length `xx` Width
×
Width
=
100
×
95
=
9500
m
Now, Area of the path = Area of the garden with path — Area of the garden
= 9500 m2 — 6750 m2 = 2750 m2
