Question

a rectangular grassy plot having dimensions 160 m into 45 M has a gravel path 2.5 M wide all rounder turn the inside find the cost of gravelling path at 75 Paisa per metre

Answer 1

area of plot = 160×45
$160 \times 45$
area of paval path = 160-5×45-5
=
$155 \times 40$
area of path with cost = 160×45-155×40 ×0.75

Answer 2

Answer:

Rs. 750

Step-by-step explanation:

Area of the plot =160×45m=7200 m²

Width of the path =2.5 m

Inner length of the plot =160−(2×2.5)=155 m

Inner breadth of the plot =45−(2×2.5)=40 m

Area of the plot excluding the path =155×40=6200 m ²

Area of the path =7200 m²  

−6200 m²  

=1000 m²  

∴ Cost of gravelling the path=1000× 100

=Rs.750
