How to easily and accurately calculate your land area
Calculating land area can be done in various steps, whether manually using a meter or ruler, or even using advanced methods like Google Maps!
If you want to build a house on a vacant plot of land, measuring the land is one of the processes that must be overcome.
The purpose of measuring the land area is to make the land level even, so that buildings erected on it do not lean.
1. The importance of accurately measuring land area
Because the purpose of measuring land area is very important, this work should not be done haphazardly.
Because even a small error could affect the calculation of costs to be incurred.
Generally, land area is measured by topographic experts using theodolite instruments.
Their services will be paid on a per-1 m² basis.
However, you can also use the same method of calculating land area to estimate the land area.
In this way, there is an estimate of the service costs incurred in paying for expert services.
If you have a plot of land and wish to measure its length and width, there are a number of methods you can follow.
They are as follows:
2. How to calculate the land area in the certificate
Well, in this way, it means your land is pre-calculated.
Therefore, you no longer need to ask a topography expert to measure the land area.
Calculate your land area and provide this information to the contractor who will build the house.
Within the land certificate there is information called the status image of the land plot.
This information is found on page 6 of the land certificate sheet.
Each certificate has a different picture of the situation, depending on the shape of the land you have.
How to measure land area using a certificate, use a ruler measuring tool.
Each certificate has a different scale. First of all, pay attention to the numbers on the scale.
Formula:
Actual length: Long distance on the certificate: scale
Actual display: Map view (plan): Scale
Surface area: Actual length × Actual width
Example :
Your plot of land is rectangular in shape, with a floor plan measuring 6 cm in length and 2 cm in width. The scale on the plan is 1:500.
Actual length: 6 cm: 1/500 = 3000 cm = 30 meters
Actual width: 2 cm: 1/500 = 1000 cm = 10 m
Land area: 30 meters x 10 meters = 300 square meters
Using the method above, it can be observed that the land area of your house is 300 square meters.
If your land is not certified, you can use manual methods such as using a meter.
3. How to calculate the area of unauthorized land using a meter
Use a measuring tape to measure the length and width of the soil. This method is only for measuring rectangular soils.
How to calculate the area of a rectangular plot of land
equation:
Length x Width
example:
Length: 5 meters
Width 6 meters
Land area: Length × Width = 5 m × 6 m = 60 m²
This method is very easy because the ground is rectangular in shape.
How to calculate the area of a triangular piece of land
equation:
S = (A + B + C): 2 and L = [S x (SA) x (SB) x (SC)]
example:
A triangular plot of land measuring 8 meters x 6 meters x 10 meters, and how to calculate it:
A = 8 meters
b = 6 meters
C = 10 meters
S = (8 meters + 6 meters + 10 meters) / 2 = 12 meters
Land area = [12x (12-8) x (12-6) x (12-10)] = 24 m².
How to measure the area of irregular land
But in reality, the shape of the Earth is not always square or rectangular.
Sometimes there is land that is irregularly shaped, trapezoidal, or triangular.
First, divide the entire soil into sections so that it looks like several irregular triangles side by side.
After that, only then can you calculate the land area by calculating the area of each of the triangles.
equation:
Q = (A + B + C): 2
L = [sx (sa) x (sb) x (sc)]
Information:
Q = Half the perimeter of the triangle
abc = length of two sides of the triangle
L = Area of the triangle
example:
If you calculate it manually, just enter the numbers above into the formula.
This is an example of calculating the area of triangle 1:
s = (3 + 5 + 5.9560): 2 = 6.9780
L = [6.9780 x (6.9780-3) x (6.9780-5) x (6.9780-5.9560)] = 7.4909 m²
And so on until the area of the entire triangle is known.
For example, there are five triangles and the area of each triangle is as follows:
7.4909 + 27.5465 + 26.8069 + 24.3133 + 9.8943
Add up all the numbers to get the area of the land.
That is, the land area = 96.05 square meters .
4. How to calculate land area using Google Maps
Calculating the area using the manual method is indeed more accurate.
However, for those who just want to get an estimate, or don't have enough time to go out into the field, you can use Google's help.
This is how:
1. Open Google Maps via a web browser
2. Click on the satellite image to change the view to satellite mode or Earth mode because you will see the condition of the Earth to be measured.
3. Enter the address of the land plot to be measured in the search box on the left.
4. When the location is correct, adjust the maximum magnification or as needed, at least 1:5000
5. Click on "Measure Distance" or "Measure Distance", then click on the edges of the land or the outer boundary of the land you want to measure at several points, then return to the beginning.
6. There is "Total Area" information, which shows the area of land that was selected.
7. There is also information about the total distance, which shows the circumference of the Earth.
5. How to calculate land area using the program
In addition to using the methods mentioned above, you can also use software To calculate the land area.
AutoCAD
AutoCAD is software It was developed by Autodesk.
This program can make it easier for you to calculate land area because it can be used on devices. The mobile phone .
Just download software It's on the device mobile phone Or the computer, then follow these steps:
1. Draw a floor plan with multiple lines so that all the lines meet.
2. Block all lines by clicking on the drawn lines. The straight line will become dotted.
3. Operation In the command section , type "li" and then press Enter on Keyboards. The drawn land area will also appear.
Geographic area calculator
In the Geo Area Calculator app, there is Filed Measure, which is a smart measurement tool for measuring areas on the map.
This app contains a GPS area with various types of Map View, satellite and livelihood maps.
These are several ways to calculate land area that can be done; I hope this article is helpful to you!
