Question

15. A garden is 90m long and 75 m wide is to be built all around it along its border.
Find the area of the path.

Answer 1

$\huge{SOLUTION:}$

Length (l) of garden = 90 m

Breadth (b) of garden = 75 m

Area of garden = l × b

= 90 × 75 = 6750 m2

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 the garden including the path =

100 × 85 = 8500 m2

Area of path = 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
