Question

A rectangular park is 90 m long and 75 m
wide. A path 5 m wide is constructed
outside the park. Find the area of the path.​

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 m2

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
