A rectangular plot measures 125 m by 78 m. It has a gravel path 3 m wide all around on the outside. Find the area of the path and the cost of gravelling it at Rs.75 per $m^{2}$ .

Open in App

Solution

area of path = area of whole field - area of rec. plot

= 131 $\times$ 84 - 125 $\times$ 78

=11004 - 9750

= 1254 $m^{2}$

cost of gravelling = 1254 $\times$ 75

=Rs. 94050
