How to calculate the area of a room using roulette

Sometimes, in order to find an answer to a seemingly simple question, one has to resort to the help of the Internet. This is not surprising, especially if we take into account the amount of useless information that students and students are hammered on. A person can remember how to calculate the integral, but forget how to calculate the area of a room. It is this issue that will be the topic of our today's article.

The only way

In fact, how to calculate the area of the room, there is nothing complicated. There is only one way to calculate. It consists in the fact that it is necessary to multiply two quantities - length and width. Or, with respect to the walls, - the height to the width. In general, without the definition of the area it is impossible to accurately calculate how much the repair of the room is worth, since the amount of materials for finishing is chosen precisely on the basis of the value obtained.

Tools and solutions

In the articles on the topic: "How to calculate the area of the room?" Usually indicate two tools with which you can perform measurements - this is the usual roulette or, if there is, a laser rangefinder. Although the majority have only the first, the accuracy obtained is quite sufficient for measurements.

So, let's imagine that you need to figure out how to calculate the area of a room in which there is one door and one window. First we measure the height of a solid wall from floor to ceiling. Then from the opposite walls, stretching the tape of the tape measure over the skirting board. The obtained values in meters are multiplied, and the area of this section of the room is obtained. The same is done with respect to all the other three sides (if the room is rectangular). The next step is to take into account the door and the window. In the same way, with the help of a tape measure, measurements of the length and width of the openings are taken and their area is calculated. Since these elements do not need finishing, then from the total amount of areas, the values of the openings are subtracted.

Often, apart from walls, you have to measure the ceiling. Since the walls can be located at a small angle, invisible to the eye, if you try to calculate the ceiling area, based on the size of the floor, you can get the wrong data. Therefore, for correct determination, it is necessary to measure each element separately. This is especially important when it is planned to renovate the bedroom, where the ceiling is one of the most viewed surfaces.

When calculating it is necessary to take into account possible protrusions of walls and niches. All these elements are calculated separately and their surface area is added to the main one.

Remember the geometry

Although most rooms are rectangular in shape, sometimes triangular, and even semi-circular rooms are found. In the first case, it is necessary to measure the lengths of two sides forming a right angle, multiply these two numbers and divide them by 2. For a circular room, use another formula: measure the diameter (the distance between two opposite points of the circle passing through the center), then multiply the resulting number On itself (square) and multiply by the famous number Pi, equal to 3.14. The result will only be divided into four - this will be the area.

As you can see, there is nothing difficult in determining the area. It will take only a little time, tape measure, as well as a pen and a blank sheet of paper to record the results.
