How to use the formulas of receivable area and paid-in area of property fees?

Property fee = property use area * unit area rate

There are standards for property fees. Just multiply the charging standard by the building area of your house. For example, the standard is 1.5 yuan, and the area is 100 square meter. As long as 1.5 is multiplied by 100, the monthly property fee is 150 yuan, and one year is 1800 yuan. And so on.
