Question

a garden is 90m long and 75m broad . A path 5m 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

Answer:

Area of original garden =90×75=6750 m

2

After path is added around rectangle, new length =90+2×5=100 m

New breadth =75+2×5=85 m

Area of rectangle with path =100×85=8500 m

2

So,

Area of path = Area of rectangle with path − Area of rectangle without path

Area of path =8500−6750

=1750 m

2

We know,

1 m

2

=0.0001 hectare

So,

6750 m

2

=6750×0.0001

=0.675 hectare

Hence area of ground =6750 m

2

=0.675 hectares

Answer 2

Step-by-step explanation:

Given:

• Length of garden= 90m
• Breadth of garden= 75m
• Path= 5 m

.°. Area of original rectangle= ( 90×75)m²

= 6750m²

After path is added around rectangle, new length

={ 90+(2×5)}= 100 m

New breadth={ 75+(2×5)}= 85 m

.°. Area of rectangle with path= (100×85)m²

= 8500 m²

So,

Area of Path=Area of rectangle with path- Area

of original rectangle

==》Area of Path= (8500-6750) m²= 1750 m²

Thus, the area of path is 1750 m².

We know that

1m²=0.0001 hectare

So,

6750 m²= 6750×0.0001

=0.675 hectare

Hence Area of garden=0.675 hectare.
