Answer:
36
Step-by-step explanation:
Given the vertices of the triangle as A(-7, -4), B(1, 11), and C(-7, 5).
To be able to determine the perimeter of the triangle, we have to first find the distance between the vertices using the distance formula.
Let's determine the distance between A(-7, -4) and B(1, 11) as seen below;
Let's also determine the distance between B(1, 11) and C(-7, 5);
Let's determine the distance between C(-7, 5) and A(-7, -4);
To find the perimeter of the triangle, we'll add the distance between each vertex together;
