It is important to note that there are different ways to calculate the area of a hexagon. However, the simplest method which I am going to talk about is used mostly for regular hexagons. By regular hexagons, I mean the length of the six sides is the same.
Once you are able to determine that the hexagon you have in front of you has six equal sides, you can use this formula, i.e., Area = (3√3 s² )/ 2. Since you now have the formula to use, all you need to do is to substitute the value for the length of one of the six sides into the equation.
For instance, let's assume the length of one of the six sides is 4cm, and it's the same for all the six sides, then: A= (3√3 4²)/2. At this point, all you need to do is to simplify the answer and determine the value of "A." At the end of everything, you should get 41.57cm².
