A rectangular park is 45 m long and 30 m wide. A 2.5 m wide path is constructed all along outside the park. The area of the path is :
Answer & explanation
Correct answer: option 3
Area of park =l×b=45×30=1350cm2
Area of park including path =(45+2.5+2.5)×(30+2.5+2.5)=1750cm2
Therefore,
Area of path = Area of park including path − Area of rectangular park
=1750−1350=400cm2.
