If you plan to make repairs yourself, then you will need to draw up an estimate for construction and finishing materials. To do this, you need to calculate the area of โโthe room in which you plan to carry out repairs. The main assistant in this is a specially developed formula. The area of โโthe premises, namely its calculation, will allow you to save a lot of money on building materials and direct the freed up cash resources to a more needed channel.
Geometric shape of the room
The formula for calculating the area of โโa room directly depends on its shape. The most typical for domestic structures are rectangular and square rooms. However, during the redevelopment, the standard form may be distorted. The rooms are:
- Rectangular
- Square.
- Complex configuration (e.g. round).
- With niches and ledges.
Each of them has its own calculation features, but, as a rule, the same formula is used. The area of โโthe room of any shape and size, one way or another, can be calculated.
Rectangular or square room
To calculate the area of โโa room of a rectangular or square shape, it is enough to recall school geometry lessons. Therefore, it should not be difficult for you to determine the area of โโthe room. The calculation formula has the form:
S rooms = A * B, where
A is the length of the room.
In - the width of the room.
To measure these values โโyou will need a regular roulette. To get the most accurate calculations, it is worth measuring the wall on both sides. If the values โโdo not converge, take the average value of the resulting data as a basis. But remember that any calculations have their own errors, so the material should be purchased with a margin.
Complex room
If your room does not fall under the definition of "typical", i.e. has the shape of a circle, triangle, polygon, then perhaps for calculations you need a different formula. The area of โโa room with such a characteristic can be arbitrarily divided into rectangular elements and calculations can be made in a standard way. If you do not have such an opportunity, then use the following methods:
- The formula for finding the area of โโa circle:
S room = ฯ * R 2 , where
ฯ = 3.14;
R is the radius of the room.
- The formula for finding the area of โโa triangle:
S room = โ (P (P - A) x (P - B) x (P - C)), where
P is the semiperimeter of the triangle.
A, B, C are the lengths of its sides.
Hence P = A + B + C / 2
If you have any difficulties in the calculation process, it is better not to torture yourself and turn to professionals.
The area of โโthe room with ledges and niches
Often walls are decorated with decorative elements in the form of various niches or ledges. Also, their presence may be due to the need to hide some unaesthetic elements of your room. The presence of ledges or niches on your wall means that the calculation should be carried out in stages. Those. First, there is the area of โโa flat section of the wall, and then the area of โโa niche or ledge is added to it.
The area of โโthe wall is according to the formula:
S walls = P x C, where
P - perimeter
C - height
You must also consider the presence of windows and doors. Their area must be subtracted from the resulting value.
Room with multi-level ceiling
The multilevel ceiling does not complicate the calculations as much as it seems at first glance. If it has a simple structure, then it is possible to make calculations on the principle of finding the area of โโwalls complicated by niches and ledges.
However, if the design of your ceiling has arcuate and wave-like elements, then it is more advisable to determine its area using the floor area. To do this, you must:
- Find the dimensions of all straight sections of the walls.
- Find the floor area.
- Multiply the length and height of the vertical sections.
- Sum the resulting value with the floor area.
Step-by-step instructions for determining the total
premises area
In order to correctly calculate the area of โโyour room, you will need not only a certain formula. The area of โโthe premises is measured in stages within a strict sequence, which includes the following items:
- Free the room from unnecessary things. During the measurement process, you will need free access to all parts of your room, so you need to get rid of everything that can prevent this.
- Visually divide the room into sections of regular and irregular shape. If your room has a strictly square or rectangular shape, then this step can be skipped.
- Make an arbitrary layout of the room. This drawing is needed so that all the data is always at your fingertips. Also, it will not give you the opportunity to get confused in numerous measurements.
- Measurements must be made several times. This is an important rule to avoid calculation errors. Also, if you are using a laser tape measure, make sure that the beam lies flat on the wall surface.
- Find the total area of โโthe room. The formula for the total area of โโthe room is to find the sum of all the areas of individual sections of the room. Those. S total. = S walls + S floor + S ceiling
