A rectangular grassy plot is 75 metre long and 60 metre broad. It has a path of width 2 metre all around it on the inside. Find the area of the path and the cost of constructing it at rupees 125 per metre square.
Answers
Length of plot =75m
Breadth of plot =60m
Area of plot =l×b
=75×60=4500m^2
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=4774m^2
Therefore, Area of path = Area of plot including path − Area of plot only
∴ Area of path =4774−4500=274m^2
Given that cost of constructing path is Rs.125 per square meter.
Therefore, Cost of constructing path around plot=125×274=Rs.34250.
