You can identify that the height is:
The area of a triangle can be found with this formula:
Where "b" is the height of the triangle and "H" is its height.
Knowing this formula, you can find the area of the base of the prism. This is:
Since the perimeter of a figure is the sum of the lenghts of its sides, "p" is:
Therefore, substituting values into the formula, you get:
