Question

A rectangular grassy plot is 75 m long and 60 m broad. It has a 2 m wide path all around it. Find the area of the
path and the cost of graveling it at 3.60 per sq.m.
​

Answer 1

Answer:

75 * 60 = 4,500

So, 75 - 2 - 2 = 71

60 - 2 - 2 = 56

71 * 56 = 3976

Area of the path = 4500 - 3976 = 524

Cost of gravelling = 524 * 3.60 = 1886.4

Answer 2

Answer:

Step-by-step explanation:

Length of plot =75m

Breadth of plot =60m

Area of plot =l×b

=75×60=4500 m power square .

 

Now,

Width of path =2m

Therefore,

Length of plot including path =75+2=77m

Breadth of plot including plot =60+2=62m

Therefore,

Area of plot including plot =77×62=4774 m power square

 

Therefore,

Area of path = Area of plot including path − Area of plot only

∴ Area of path =4774−4500=274 m power square

 

Given that cost of constructing path is Rs.125 per square meter.

Therefore,

Cost of constructing path around plot=125×274=Rs.34250.
