How to calculate square meters - just about complicated

Calculation tools

Repair in a room always requires knowledge of the exact area of the floor, balcony, bathroom, walls. Thus, knowing the size of the area, you can accurately buy the right amount of materials, and calmly carry out repairs. This article is to answer the question: “How to calculate square meters?”, And how much time will you need for this.

Why calculate the area of a room?

A variety of factors can serve as a motive for calculating the area of \u200b\u200ba room, but for the most part this is due to renovations in the room. The most common pretext for mathematical calculation is:

Scheduling work related to the installation of suspended ceilings, when there is a need to know the amount of material to complete the work
When installing stretch ceilings, you should also be aware of the area in order to calculate material resources for repairs
Painting and scraping the ceiling is no exception and requires knowledge of measurements, because all paintwork and primers are analyzed per m2
When finishing plasterboard walls, there is also a need to know the area of \u200b\u200bthe wall in the room
When hiring workers, for example, to install a stretch ceiling, their amount of work will depend on each square meter of your ceiling!
When selling a house or when decorating it, you need to know how to measure the area of the shelf, walls, ceiling.

How to calculate floor area?

So how do you calculate square meters? The easiest to formulate floor area is a square and rectangular house. To calculate the area of \u200b\u200bsuch a room, it is necessary to measure the length and width of the room (measured in meters), and then multiply these two numbers by each other, getting the number of interest to us. This option is not difficult to implement, it does not require rearranging the sofa, wardrobe and other furniture - just enough to calculate the distance. The only problem will be the fireplace (if there is one, of course) in this case, from the final figure, it will be necessary to subtract the S (area) of the fireplace.

Formula: S rooms \u003d A x B, where A is the length, B is the width.

Irregularly shaped rooms represent a more complex calculation of the S floor. An apartment that has the shape of a rectangle or square is called standard, however, if there are decorative changes (arches, niches), then the calculation is more complicated, since it requires the calculation of S figures that make up the room.

First, the plan must be divided into two rectangles, and then sum their areas

By calculating the total area of “non-standard figures”, for example, an L-shaped room, you can “break” the room into two squares or triangles and sum up their sum, such a little trick allows you to find out S of this area in a matter of minutes without any mathematical calculation formulas. In some cases, the corner of an L-shaped room does not transition at a 90º angle, which is a small but manageable snag. Crossing at an oblique angle, the transition looks like a triangle, the calculation must be carried out according to the familiar geometric law: "The area of \u200b\u200bthe triangle is equal to the first leg multiplied by the second."

Cylindrical and semi-segmented particles, but how to calculate square meters based on the basic course of algebra and geometry? It is much easier to divide the plot into conditional triangles and squares, and then do the calculation and summation the results of each individual element.

Formulas for area, geometric shapes

There are living rooms in private houses with different floor heights (ledges, hills, slopes). To perform the calculation, it is necessary, as in the previous case, to divide the areas into separate elements, measuring each separately and summing up the results.

Roulette is the best tool to help you calculate the S of the floor. However, in addition to the tape measure, you need to take a piece of paper and a pencil and write down the measurements, and only then carry out mathematical calculations (so as not to confuse and measure everything ten times).

Advice

Do not take measurements on the wall, as it may be defective and lead to inaccurate measurements. Places with protrusions in the form of semicircles or zigzags should be counted separately.

Calculating the area of a rectangular room and ceiling

Rectangular room is the easiest option for any dimension. To measure the ceiling, you do not need to reach it at all with the help of a ladder, but remember one important thing, assuming that S of the floor \u003d S of the ceiling.

Task for a 5th grader. The area is equal to the product of length and width.

How to calculate the area of a room in which there are niches and ledges?

To determine how much m 2 such a room has is a painstaking work that requires a number of actions and time spent, namely:

Make a room plan
Measure the height and length of the room on flat walls
Divide space into even shapes
Sum Results

The formula for the room is not the correct shape

Calculation of the area of a room with multi-level ceilings

Using the calculation method of the above "individual elements" method in this case is an inaccurate and complex method, much simpler and better:

Measure walls (in straight sections)
Determine S gender
On each vertical section, multiply the height by the length
Add to gender

The formula for the total area of a room

Clear the space near the walls (measurement accuracy will increase).
Identify areas with the correct shape
Make a plan of the room to make it easier to work.
Find out the length, width, height of the room
Add up the areas of the calculated plots.

The concept of "minimum room area" and its calculation

Sections of the room in the form of a triangle, rectangle, circle - are calculated according to standard geometric formulas. After that, the results are rounded up.
