Question

3. A rectangular park is 45 m long and 30 m wide. A path 2.5 m wide is
constructed inside the park. Find the area of the path. Find the cost of
paving the path at 11 per m2.
​

Answer 1

Step-by-step explanation:

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
