Answer:
12
Step-by-step explanation:
The area of the base of the triangular prism is the area of the triangle. So, it can be calculated as:

Where the base is 4 cm and the height is 6 cm. So, replacing the values, we get:
![\text{Area = }\frac{4\operatorname{cm}*6\operatorname{cm}}{2}=(24cm^2)/(2)=12cm^2]()
Therefore, the area of the base of the prism is 12 square cm
