Cracking your head over equilateral triangles? We feel your *acute* pain! But don’t worry, we’re here to slice through the confusion with a little bit of humor and a lot of clarity. Let’s get to it!

**Formula:**

```
(√3/4) * side^2
```

This is the industry standard formula to calculate the area of an equilateral triangle. Here, the “side” refers to the length of one side of the triangle.
