Question

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.​

Answer 1

Length of rectangular garden = 90 m and breadth of rectangular garden = 75 m

Outer length of rectangular garden with path

= 90 + 5 + 5 = 100 m

= 75 + 5 + 5 = 85 m

Outer area of rectangular garden with path = length x breadth = 100 x 85 = 8,500 m^2

Inner area of garden without path = length x breadth = 90 x 75 = 6,750 m^2

Now Area of path = Area of garden with path – Area of garden without path = 8,500 – 6,750 = 1,750 m^2

Since, 1 m^2 =1/10000 hectares

Therefore, 6,750 m^2 = 6750 = 0.675 hectares

Answer 2

Solution :-

Length of garden ➪ 90 m

Breadth of garden ➪ 75 m

Area of garden » l×b

↳ 90×75m^2

↳ 6750 ÷ 10000 m^2

↳ 0.6750 hectare

» Length of garden with path » 90+5+5

» 100

» Breath of garden with park » 75+5+5

» 85

⁂ Area of garden with park » 100×85

» 8500

Area of path ➪ 8500 - 6750m^2

↳ 1750 m^2
