To find the area of the bases of the triangular prism, we first need to find the area of each triangular base.
Using the formula for the area of a triangle, which is 0.5 * base * height, we can calculate the area of the first triangular base:
Area = 0.5 * 3 * 5 = 7.5 square centimeters
Next, we can calculate the area of the second triangular base:
Area = 0.5 * 11 * 4 = 22 square centimeters
Since there are two bases in a triangular prism, we need to find the total area by adding the areas of the two bases:
Total Area = 7.5 + 22 = 29.5 square centimeters
Therefore, the closest option to the total area of the two bases of the triangular prism is B. 12 square centimeters.
