A garden is $90\ m$ long and $75\ m$ broad. A path $5\ m$ wide is to be built outside and around it. Find the area of the path. Also find the area of the garden in hectare.
Given:
A garden is 90m long and 75m broad. A path 5m wide is to be built outside and around it.
To do:
We have to find the area of the path.
Solution:
Area of the garden = $90\times75\ m^2$
$=6750\ m^2$
Area of the outer rectangle including the park = $(90+5+5)\times(75+5+5)\ m^2$
$=100\times85\ m^2$
$=8500\ m^2$
Therefore,
Area of the path = Area of the outer rectangle $-$ Area of the garden
$=(8500-6750)\ m^2$
$=1750\ m^2$.
