For professionals it is, of course, simpler.They have an eye and a tool, and there is a tool. But those who do not have a construction education, but because of the circumstances decided to do their own repairs, sometimes you have to break your head over the simplest, seemingly, tasks. Here, for example, such a question: how to find out the area of the room? And now the philistine nervously draws lines on paper or paces the room back and forth, pulling a meter tape measure ... Eh, it was necessary to listen carefully to the teacher of geometry!
But there is no time for lyrics - repair itself will not become. Therefore, we will quickly consider all the nuances, but at the same time we will talk about the cases when in general this very area of the room is so necessary.
Equipment
Before proceeding with the removal of the measurements, we will arm ourselves with the following simple devices:
- tape measure or centimeter tape;
- a pencil or a crayon;
- notebook with pen;
- calculator.
Take care that everything is at hand.Do not rely on memory and the phenomenal abilities of an oral account - just write down the numbers and count on the calculator. The values obtained will most likely not be round, working with them in the mind will not be easy.
Tooltip from the tutorial
The formula of the square is one of the few knowledge gained in the school that most people remember all their lives. You just need to multiply the length and width - nothing complicated.
Therefore, before you know the area of the room, just measure the length of the walls. The resulting values are multiplied, and here it is the result!
"But not all rooms are in the form of a rectangle and a square", - the inquisitive reader will certainly notice ... That's right, so let's try to turn the focus and in the premises of an unusual layout.
A circle
Modern architecture sometimes amazesnon-standard solutions, so do not think that the round can be unless the throne room in the castle of the pretentious king or the hall in the hotel. Faced with this may, for example, the owner of housing in a fashionable new building or the person who bought an apartment after re-planning. Again, we remember the course of geometry and write the formula in the notebook: S = πR².
In practice, it is easier to measure diameter than to findradius, because for the latter you need to know exactly where the center is. And to find the diameter, simply fix the edge of the measuring tape near one wall, move to the opposite and by trial and error, find the point as far removed from the beginning of the tape.
Divide the resulting value in half, square it and multiply it by 3.14. This is the area of the round room.
How to find the area of the room of irregular shape
We will analyze the example for greater clarity. Let's say that we have a small apartment, a "hotel", in which we need to know the area of the living room:
We do the following:
- we measure wall 1 and wall 2, write down the values obtained;
- multiply x: 7 x 3.5 = 24.5 (m2);
- we measure the walls number 3 and 4;
- multiply: 1.5 x 2.5 = 3.75 (m2);
- subtract from the first value obtained "excess area": 24.5 - 3.75 = 20.75 (m2).
As you can see, nothing complicated again!
Scope of application
And why are we even trying to figure out how to find outsquare room in square meters? Let's decide for the calculation of which materials it is useful. Of course, we are talking about materials for the floor and ceiling. So, this value is needed when applied:
- plaster mix;
- primer, putty;
- paint;
- liquid wallpaper;
- textured plaster;
- varnish;
- substrate under the laminate flooring;
- waterproofing roll materials;
- Styrofoam.
Calculating the consumption of material, we often (but not always!) Proceed from the area.
When it is not useful
Выбирая некоторые виды отделки, можно и вовсе не think about how to find out the area of the room. Why? Yes, because we will not do the joint wallpaper in the middle of the ceiling or collect a mosaic of linoleum. Relying on the area, it is easy to make a mistake when buying, therefore for rolled finishing materials we need the linear dimensions of the walls - we will count by the number of whole strips. Such materials include:
- wallpaper;
- carpet;
- linoleum;
- false ceiling type "Armstrong";
- stretch ceiling.
Floor coverings (laminate, parquet) are no exception. This value is in most cases informative for small tiles, but the larger one is better to recount, based on the length and width of the room.
Wall area
By the same principle that we used whencalculating the area of the room of irregular shape (dormitories), you can easily calculate the area of the walls Knowing the length and width of the room, calculate its perimeter, multiply by the height. We obtain the total surface area, from which we then subtract the area of windows and doors.
But a little trick on how to find outthe area of the walls of the room, pasted over with typical wallpaper. If you can see the joints between the bands, count their number. Divide by 2 and get the perimeter in meters. The fact is that the width of the roll of wallpaper is a little over 50 cm. Therefore, you do not have to walk along the walls with a tape measure before you find out the perimeter of the room.
Knowing the area and the linear dimensions of the room, it is easy to calculate the amount of materials needed for the repair, even without the help of professionals.
