Answer:₹6200
Step-by-step explanation:
dimensions of the lawn = 30 × 28
dimensions of the lawn with the path = 30 + 2 + 2 × 28 + 2 + 2
=34×32
area of only the lawn = 30 × 28
= 840 m²
area of the lawn with the path = 34 × 32
= 1088 m²
so,
area of the path = (1088 - 840) m²
= 248 m²
rate of levelling the path = ₹25/m²
so total cost = ₹(248 × 25)
= ₹6200(ans)
hope it helps!
