Q.1 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: Length = 90 m

Breadth = 75 m

Area of the garden = l × b

= 90 m × 75 m = 6750\( m^2 \)

Length of the garden including path

= 90m + 5m + 5m = 100 m

Breadth of the garden including path

= 75m + 5m + 5m = 85m

Area of the garden including path
= l × b

= 100 m × 85 m = 8500 \( m^2 \)

Area of the path = 8500 \( m^2 – 6750 m^2 = 1750 m^2 \)

Hence, required area of path = \(1750 m^2\) and area of the garden =\( 6750 m^2 = 0.675 hactare \)
