<u>jAlright, let's take this problem step-by-step</u>:
<u>What is the perimeter</u>:
⇒ all the side-lengths added up
⇒ <em>need</em> to find side-length using distance formula
- (x₁,y₁): first point
- (x₂,y₂): second point
<u>Let's solve</u>:
- Find length of <em>AC</em>
⇒ <em>first point</em>: (5,7)
<em> ⇒ second point: </em>(3,3)
<em> </em>
- Find length of AB
⇒ <em>first point:</em> (5,7)
<em> ⇒ second point:</em>(8,6)
<em> </em>
- Find length of BC
⇒<em> first point: </em>(8,6)
<em> ⇒ second point: </em>(3,3)
<em> </em>
<u>Now let's solve for the perimeter</u>:
<u>Answer: 13.43</u> (<em>rounded to the nearest hundredth)</em>
