Answer:
Rs.5760
Step-by-step explanation:
Given:
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
