A triangle is shown on the coordinate plane below. What is the perimeter of this triangle rounded to the nearest tenth of a unit?
A
32.0 units

B
34.0 units

C
37.5 units

D
40.4 units

32.0 unite

Step-by-step explanation:

The triangle is shown in the attached figure, and have three vertices: , and .

Each vertice represents a point in the cartesian plane and the length of each side of the triangle is the modulus of each vector.

In this sense, the modulus is calculated as shown:

Hence, for each vector:

Now, the perimeter of a triangle is the sum of its three sides:

Finally:
