Question

A garden is 90 m long and 75 m broad.A path 5m wide is to be built outside and around it. Find the area of path.Also find area of garden in hectares

Answer 1

Length (l) of garden = 90 m
Breadth (b) of garden = 75 m
Area of garden $=l\times b=90\times 75=6750m^2$
From the figure, it can be observed that the new length and breadth of the garden, when path is also included, are 100m and 85m respectively.
Area of path = Area of the garden including the path - Area of garden
$=8500-6750=1750m^2$
1 hectare = $10000m^2$
Therefore, area of garden in hectare
$=\frac{6750}{10000}=0.675hectare$
