Question

5. A rectangular park is 60 m by 30 m. A path 5 m wide is built all around inside it. Find the cost of constructing the path @ 200 per m².​

Answer 1

Answer:

Area of park =l×b=45×30=1350 cm

2

Area of park with path is =45+2.5+2.5×30+2.5+2.5=1750 cm

2

Therefore,

Area of path = Area of park with path − Area of rectangular park

=1750−1350=400 cm

2

Hence, this is the answer

Answer 2

Answer:

Area of park =l×b=45×30=1350 cm  

2

 

Area of park with path is =45+2.5+2.5×30+2.5+2.5=1750 cm  

2

 

Therefore,

Area of path = Area of park with path − Area of rectangular park              

=1750−1350=400 cm  

2

 

Hence, this is the answer.
