Question

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 hectares

Answer 1

Length (l)of garden = 90 m

Breadth(b) of garden = 75 m

Area ofgarden = l × b = 90 × 75 = 6750 m2

From thefigure, it can be observed that the new length and breadth of thegarden, when path is also included, are 100m and 85m respectively.

Area ofthe garden including the path = 100 × 85 = 8500 m2

Area ofpath = Area of the garden including the path − Area of garden

= 8500 − 6750 = 1750 m2

1 hectare= 10000 m2

Therefore,area of garden in hectare 

=6750/10000 =0.675 hectares

Answer 2

Length (l)of garden = 90 m

Breadth(b) of garden = 75 m

Area ofgarden = l × b = 90 × 75 = 6750 m2

From the figure, it can be observed that the new length and breadth of thegarden, when path is also included, are 100m and 85m respectively.

Area ofthe garden including the path = 100 × 85 = 8500 m2

Area ofpath = Area of the garden including the path − Area of garden

= 8500 − 6750 = 1750 m2

1 hectare= 10000 m2

Therefore,area of garden in hectare

=6750/10000 =0.675 hectares
