Answer» length(l) of lawn = 50m breadth(b)of lawn = 36m width of path = 2m so the, length(L) of outer rectangle = 50+2+2 = 54m breadth(B) of outer rectangle = 36+2+2 = 40m Area of path =Area of outer rectangle - Area of inner lawn = L×B - l×b = 54×40 - 50×36 = 2160 - 1800 =360m^2 Cost of levelling path = 360×16 =Rs.5760 Thanks |
