In a triangle ABC, if 𝑡𝑎𝑛 𝐴 = 1/2,𝑡𝑎𝑛 𝐵 = 1/3 , 𝑎𝑛𝑑 𝑡𝑎𝑛 𝐶 = 1/4, find the area of the triangle.

To find the area of the triangle \(ABC\) given the values of \(\tan A = \frac{1}{2}\), \(\tan B = \frac{1}{3}\), and \(\tan C = \frac{1}{4}\), we can use the formula involving the tangent of the angles and the semiperimeter \(s\).

### Step 1: Use the formula for the area
The area \(K\) of a triangle can be given by:

\[
K = \frac{1}{4} \cdot \frac{abc}{R}
\]

where \(R\) is the circumradius of the triangle, and \(a\), \(b\), and \(c\) are the sides of the triangle.

However, since we have the tangents of the angles, we can use the following formula for the area involving the tangents:

\[
K = \frac{1}{4} \cdot \frac{(ab + bc + ca)}{\tan A \cdot \tan B \cdot \tan C}
\]

### Step 2: Compute the tangential area
Given the tangents of the angles:

\(\tan A = \frac{1}{2}\), \(\tan B = \frac{1}{3}\), \(\tan C = \frac{1}{4}\),

the area can be simplified as:

\[
K = \frac{1}{4} \cdot \frac{1}{\tan A \cdot \tan B \cdot \tan C}
\]

Substitute the values:

\[
K = \frac{1}{4} \cdot \frac{1}{\left(\frac{1}{2}\right) \cdot \left(\frac{1}{3}\right) \cdot \left(\frac{1}{4}\right)}
\]

### Step 3: Simplify the expression
First, calculate the product of the tangents:

\[
\tan A \cdot \tan B \cdot \tan C = \frac{1}{2} \cdot \frac{1}{3} \cdot \frac{1}{4} = \frac{1}{24}
\]

Then, calculate the area:

\[
K = \frac{1}{4} \cdot \frac{1}{\frac{1}{24}} = \frac{1}{4} \cdot 24 = 6
\]

### Conclusion:
The area of the triangle \(ABC\) is \(6\) square units.
