How to calculate the area of a room - formulas and calculation methods
it sets out the repair, you must acquire a sufficient number of wallpaper, glue, paint and other materials.To do this you need to know how to calculate the area of a room.If you understand how to obtain and apply the necessary measurements, in the future, for example, when buying or selling real estate, you will be able to calculate the area of the premises and verify documents.

Simple room rectangular or square
To learn how to calculate the area of the floor of the room, you need to determine its shape.In the room which is a rectangle or a square, it is necessary to measure the length and width values and multiplied together.You get the room area in square meters.formula by which you can c
S rooms = A x B, where A - lenght, B - width.
To measure you can take an ordinary roulette.To obtain the most accurate results, it is recommended to measure the length of the wall at the beginning and at the end and if the numbers are different, take the arithmetic average.
room in which there are niches or projections
If the room there are niches, ledges, plumbing and ventilation design, it is necessary to measure the area of each section separately.If it is a niche in the wall, then to the area of the room you need to add the area of the recess.If this projection, accordingly, the area of the room will have to subtract its area.
the same principle should be followed if you want to learn how to calculate the area of the ceiling of the room.Flat, rectangular ceiling without any protrusions and recesses means that it is necessary to measure the length and width, and then calculate the area of a simple multiplication.
If you plan to insulate the floor by means of heating elements, the total area of the floor you will need to subtract the area that is occupied by heavy furniture.
room complex configuration
Often there are rooms with unusual shapes.If possible, it is necessary to divide the room into several rectangles, find the area of each and fold.
Room area in the shape of a circle calculated by the formula:
S room = πR², where R - radius. necessary to consider how many degrees in the sector.
To calculate the area of the room using a triangular shape Heron's formula:
Skomnaty = √ (P (P -A) x (P - B) x (P - C)), where P - perimeter half triangle A, B,C - the length of its sides.
semiperimeter triangle is calculated as: P = (A + B + C) / 2

Features calculate the area of simple walls and walls, ledges and niches containing
Now let's look at such an important time, as the calculation of the area of the walls of the room.Knowing exactly this value, you can buy the right amount of wallpaper for repair.Of course, you can go to a counselor in the hardware store, and he is sure to tell you how to calculate the area of walls.There is nothing complicated: measure the length, width and height of the room.Next, calculate the area of walls according to the formula:
Ssten = P x C, where P - the perimeter of the room, C - height of the walls.
perimeter of the room is calculated by the formula:
P = (A + B) x 2, where A - the length, B - width.
For more accurate results, the total area of the walls is necessary to subtract the area of door and window openings.
area walls of the room with protrusions or recesses will be different from a simple wall area of the room.Do not forget to add value to the main area of the protruding wall or recessed portion.
Be careful when making measurements and calculations.If you use laser tape measure, then make sure that the beam was directed exactly perpendicular to the wall, or you will get a large error in the results.
