Question

A rectangular park is 50m long and 35m wide. A path of 2m wide is constructed

outside the park. Find the area of the path and the cost of constructing it at the

rate of Rs. 350 per 10 m2.

​

Answer 1

Answer:

156m

Step-by-step explanation:

If we draw the question as a diagram, we can make a big rectangle outside a smaller one. The dimensions of the inner rectangle are= 50m*35m=1950m^2.

The dimensions for the outer/bigger rectangle are

=(50+2+2)m*(35+2+2)m

=54m*39m

=2106m^2

So, the area of the path should be

=area of bigger rect. - area of smaller rect.

=2106-1950 m^2

=156m^2

Cost:-

Cost of constructing 10m^2=Rs. 350

Cost of constructing 1m^2= 350/10=35

Cost of constructing 156m^2= 35*156=Rs.5,460.
