To find the revenue that the farmer has to pay, we need to calculate the area of the land in hectares and then multiply it by the revenue per hectare.

First, let’s convert the dimensions of the land from meters to hectares. Since 1 hectare is equal to 10,000 square meters, we can calculate the area of the land in hectares as follows:

Area = (250 m * 160 m) / (10,000 m²/ha) Area = 40,000 m² / 10,000 m²/ha Area = 4 hectares

Now, we can calculate the revenue that the farmer has to pay by multiplying the area of the land in hectares by the revenue per hectare:

Revenue = 4 hectares * ₹1500/ha Revenue = ₹6000

Therefore, the farmer has to pay ₹6000 in revenue.
