14

Step-by-step explanation:

Perimeter of the ∆ = sum of the length of the 3 sides.

The length of the 3 sides can be calculated by using the distance formula, , to find the distance between the vertices of the ∆.

The coordinates of the 3 vertices are:

(-1, 3), (2, 2), (-2, -2)

Distance between (-1, 3) and (2, 2):

Let,

Distance between (2, 2) and (-2, -2)

Let,

Distance between (-2, -2) and (-1, 3)

Let,

Perimeter of triangle = 3.2 + 5.7 + 5.1 = 14.0 units
