Calculate

The total

**area****of walls**in one room is very simple.The total

**area**needs to be folded from square of all the (usually) four**walls**OK, they're all the same, but some have Windows, doors and similar structures. S=S1+S2+S3+S4.2

To find the

**area**of one**of the walls**, you should multiply the height**of the walls of the**ing on its length. If it does not, it will be the first**area**S1. Similarly, the calculated**area**of the other three**walls**S2, S3, S4. And**the area of**those**walls**, where there is, for example, window, calculated as: measured width and length of the window are multiplied by each other, it turns out**the square**window, the size of a**wall**, s is subtracted**the area of**the window, this will be**the area of**the**walls**s, where encased window, door, etc.
