Given:
The vertices of the triangle are (-10,-3), (1,4) and (-1,7).
To find:
The perimeter of the triangle.
Solution:
Distance formula:
Let the vertices of the triangle are A(-10,-3), B(1,4) and C(-1,7).
Using distance formula, we get
Similarly,
Now, the perimeter of the triangle is
Therefore, the perimeter of the triangle is 30.098 units.
