We are given a triangle setup and asked to find the shaded area of triangle $\triangle BCE$ based on the following information:

• Point $B$ is halfway between $A$ and $C$.
• The distances from $C$ to $D$, $D$ to $E$, and $E$ to $F$ are equal.
• The area of triangle $\triangle ACF$ is $180 \, \text{cm}^2$.

Step-by-step approach:

1. Area of $\triangle ACF$: The area of triangle $ACF$ is given as $180 \, \text{cm}^2$.

2. Relationship between points:

   • Since $B$ is halfway between $A$ and $C$, this suggests that $AB = BC$.
   • $C \to D$, $D \to E$, and $E \to F$ are equal distances, meaning that the line segment $CF$ is divided into three equal parts.

3. Proportions of triangles: The key observation here is that since the distances between $C$, $D$, $E$, and $F$ are equal, and the triangles share a common height (the perpendicular from $F$ to line $AC$), the areas of triangles formed between them will be proportional to their bases.

4. Find the area of $\triangle BCE$: $\triangle BCE$ shares a portion of the base $BC$ (half of $AC$) and its height goes from $E$ to line $BC$. Since $CE$ is two-thirds of the length of $CF$ (because $CE$ includes segments $CD$ and $DE$), the area of $\triangle BCE$ will be a certain fraction of $\triangle ACF$.

   Since $CF$ is divided into three equal parts, the ratio of the area of $\triangle BCE$ to $\triangle ACF$ is $\frac{2}{3} \times \frac{1}{2} = \frac{1}{3}$.

   Therefore, the area of $\triangle BCE$ is: $\text{Area of } \triangle BCE = \frac{1}{3} \times 180 = 60 \, \text{cm}^2$

Thus, the shaded area of triangle $\triangle BCE$ is $60 \, \text{cm}^2$.
