Answer:

The answer to your question is 11.4 units

Step-by-step explanation:

Data

A (-3, -1)

B ( 0, 3)

C ( 1, 2)

Perimeter = ?

Formula

d = \sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}

Process

1.- Find the length between the points

dAB = \sqrt{0 + 3)^{2} + (3 + 1)^{2}}

dAB = \sqrt{3^{2}+ 4^{2}}

dAB = \sqrt{9 + 16}

dAB = \sqrt{25}

dAB = 5

dBC= \sqrt{(1 - 0)^{2} + (2 - 3)^{2}}

dBC = \sqrt{1^{2} + (-1)^{2}}

dBC = \sqrt{1 + 1}

dBC = \sqrt{2}

dAC = \sqrt{(1 + 3)^{2} + (2 + 1)^{2}}

dAC = \sqrt{4^{2} + 3^{2}}

dAC = \sqrt{16 + 9}

dAC = \sqrt{25}

dAC = 5

2.- Perimeter

P = AB + BC + AC

P = 5 + \sqrt{2} + 5

P = 10 + \sqrt{2}

P = 10 + 1.42

P = 11.4
