The area of the triangle formed by the vertices (1, 1), (8, 1), and (5, 5) is calculated to be 14 square units using the formula for the area of a triangle based on its vertices. By substituting the coordinates into the formula, we find the area to be 14. This method effectively utilizes the positions of each vertex to arrive at the correct result.
