Answer:
Explanation:
Given vertices:
- A(-2,-3), B(-2,4), C(4, -3)
We can observe that:
1. Points A and B have same x-coordinate, it means the segment AB is vertical and its length is:
2. Points A and C have same y-coordinate, it means the segment AC is horizontal and its length is:
Since AB and AC intersect at point A, the shape is a right triangle with the base of AC and height of AB.
Use area formula to find its area:
- A = 1/2bh
- A = 1/2*6*7 = 21 units²
