# How to calculate square meters in different ways

The question of how to calculate square meters, usually arises in those cases when it is planned to carry out repairs, and technical documentation for housing is not available. Therefore, the simplest solution in this situation is by simple arithmetic and mathematical calculations to obtain a general area or some sort of separate room. There are various ways to perform such an operation. Each of them has its own advantages and disadvantages. Now let's move on to the theoretical and practical part of how to calculate the square meters.

**According to plan**

**Measurement and summation**

Not always available there is a plan for the room. In such a situation, one can not do without direct measurements. It is necessary to have a roulette for this operation (its length should be greater than the longest distance in the room), a pencil and a sheet of recording paper (a notebook or notebook may also come up). For rectangular rooms, length and width measurement is done. If they multiply each other, then we get the area. But for the round it is enough to determine its radius or diameter. In the first case, the area is equal to the square of the figure multiplied by the number "πi". For another situation, the calculation becomes a little more complicated: this will be the square of the diameter divided by 4 and multiplied by the same constant. The last option is a triangle. If it is rectangular, then it is enough to multiply its two legs with each other and divide the resulting result in half. In other cases, you need to measure 2 sides and determine the angle between them. Multiplying the length of the segments with each other, multiplying by the sine of the angle, we obtain the area. For rooms that have a complex contour, it is better to use the partitioning into the simplest parts and then sum them up. This method allows in various cases to decide the question of how to calculate the square meters.
