Step-by-step explanation:
Length of plot = 30 m
Breadth of plot = 20 m
A path 1.5 m wide is running outside a rectangular plot of grass 30m by 20m
Outer length = 30+(1.5+1.5)=33
Outer breadth = 20+(1.5+1.5)=23
Area of path = Outer area - Inner area
Area of path =(33 \times 23) - (30 \times 20)(33×23)−(30×20)
Area of path = 159 sq.m.
Cost of paving 1 sq.m. = Rs.12
Cost of paving 159 sq.m. =12 \times 159 = rs.190812×159=rs.1908
Hence the area of the path is 159 sq.m. and the cost of paving it is Rs.1908
