Question

a garden is 90m long and 75m broad. a path 5m wide is to be built outside and around it. find the area of the path. also find the area of the garden in a hectare

Answer 1

Step-by-step explanation:

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

answer =0.675 hectares.

I hope this answer is helps you❤️❤️❤️❤️
