Answer:
₹4740
Step-by-step explanation:
length(l) = 50m
breadth(b)= 25m
Wirth of the path(W)= 2m
cost of graveling= ₹15/square
area of the lawn(a)= l×b
=(50×25)m²
=1250m²
length with Wirth(L) = l+2W
= {50 +(2×2)}m
= {50+4}m
=54m
breadth with Wirth(B) = b+2W
={25+(2×2)}m
={25+4}m
=29m
area of the lawn with the path(A) = L×B
=(54×29)m²
=1566m²
Area of the path = A-a
= (1566-1250) m²
= 316m²
(therefore) cost if graveling = ₹(15×316)
=₹4740
