How to find the area of a triangle Overview
Finding the area of a triangle is very easy when you learn how to do it. If you practice it a few times you will completely master the formula.
Materials or Products required for this job
You will need 3 essential materials to get started.
Get a ruler to measure the base and height of the triangle accurately.
A calculator will be very useful to obtain the fastest result.
We will give you the last element here. It is the formula to calculate the area correctly. It is not complicated at all, you will only have to multiply and divide.
If you already have the triangle measurements, then you won’t need a ruler this time.
�How to do this job step by step without missing any step?
Follow these easy steps to get the area.
Step 1
You must know the value of the base and the value of the height of the triangle. Its base is the bottom line that supports the triangle; It is the horizontal line that you must measure with a ruler.
The height of the triangle can be achieved by making a simple line from the high point where they meet until reaching the base. The result of measuring that line will be the value of the height we are looking for.
Step 2
Let’s define the sides of the triangle to make it easier.
The high point of the triangle representing height will be side D.
The base that is the horizontal line will have two sides, the left will side B and the right will be C.
However, keep in mind that both will have the same value since they represent the base in a single line.
With these data we can start calculating.
Step 3
The formula asks you to multiply the base by the height and then you will have to divide that result by 2, you always divide by two.
For example, imagine that the measure of the base (B, C) is 9 and that of the height (D) is 6.
The letter A in this example will be the representation of the area, which is the value we are looking for.
The formula will look like this: A= (9×6)/2
A = 54/2
A = 27
Tips to keep in mind
You should know that the shape of the triangle will not always be the same. You can find one in rectangle, equilateral, scalene, isosceles, acute angle, among other different shapes.
This is why you must be clear about what is the base and what is the height, to measure its value.
The horizontal line is very easy to measure and surely you will not be confused, but in order to measure the height you should always pay attention to start at the correct point from the top of the triangle to the base.
With some triangle shapes it is usually more confusing.
You should not forget that in general the result of the area is squared.
Whenever you get a result, depending on whether it is meters, centimeters or some other measurement; You will have to specify this and square it.
For example, the result of the area is twenty-seven meters squared.
