Answer:
Given:
Length of the plot = 125 m
Breadth of the plot = 78 m
Area of plot ABCD=Length×Breadth
=125×78
=9750m
Length of the plot including the path =(125+3+3)m=131m
Breadth of the plot including the path =(78+3+3)m=84m
Now,
Area of plot PQRS including the path =
Length×Breadth=(131*84)
=11004m
Area of path = Area of plot PQRS − Area of plot ABCD=11004-9750
=1254m
Cost of gravelling =RS 75 per m
Cost of gravelling the whole path =RS (1254×75)=RS 94050
Hence, cost of gravelling the path is RS 94050.
