Answer:
dimensions of the rectangular grassy plot = 100m × 65m
area of the plot = (100×65)m²
= 6500m²
gravel path is on the inside
so length of the plot without the path = 100 - 2.5 - 2.5
= 95m
breadth of the plot without path = 65 - 2.5 - 2.5
= 60 m
area of the plot without the path = (60 × 95)
= 5700 m²
⇒area of the path = (6500-5700)m²
= 800 m²
rate of cost = 80p/m²
so total cost = ₹(800×80)/100
= ₹640(ans)
