Question Analysis

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

Key Concept Explanation

The area of a triangle is given by 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. Find the base:

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