Question Analysis

The main focus is recognizing the figure as a triangle and applying the formula to find its area, using the coordinates of the vertices to determine the base and height.

Key Concept Explanation

The area of a triangle is calculated using the formula , where is the length of the base and is the perpendicular height from the opposite vertex to the base.

Step - by - Step Solution

1. Determine the base:

Points and have the same - coordinate. The length of the base (the distance between and ) is .

2. Determine the height:

The - coordinate of (and ) is 5, and the
