Answer:

Option B, 14.6 units

Step-by-step explanation:

<u>Step 1: Find the distance of AB</u>

<u /> $AB =$ $\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$AB =$ $\sqrt{(3 - 1)^2 + (5 - 3)^2}$

$AB =$ $\sqrt{(2)^2 + (2)^2}$

$AB =$ $2\sqrt{2}$ or 2.83...

<u>Step 2: Find the distance of BC</u>

$BC =$ $\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

<u /> $BC = \sqrt{(3 -1)^2 + (-1 - 3)^2}$

$BC = \sqrt{(2)^2 + (-4)^2}$

$BC = \sqrt{4 + 16}$

$BC = \sqrt{20}$

$BC = 2\sqrt{5}$ or 4.47...

<u>Step 3: Find the perimeter</u>

<em>AB is the same as AD and BC is the same as DC</em>

<em /> $2(AB) + 2(BC)$

$2(2.83) + 2(4.47)$

$5.66 + 8.94$

14.6 units

Answer: Option B, 14.6 units
