Question 625736
Use <a href="http://www.algebra.com/algebra/homework/Coordinate-system/hummingbird-distance-2D.solver">this solver</a> to find the distance between P and Q to get <font color="green">8.5440037 units</font> (this is approximate)



Note: this solver will walk you through the formula and the steps needed to find the distance between any two points.



Use the same solver to find the distance between Q and R to get <font color="blue">17.8044938 units</font> (approximately)



Finally, use the same solver again to find the distance from P to R to get <font color="purple">10 units</font>




Now add up the three distances: <font color="green">8.5440037</font> + <font color="blue">17.8044938</font> + <font color="purple">10</font> = 36.3484975


This rounds to <font color="red">36.35 units</font>



So....


Which of the following is the closest approximation of the perimeter of triangle PQR given P(4, 5), Q(-4, 2), and R(10, 13)?


a. 37.38
<font color="red"><b>b. 36.35</b></font>
c. 22.14
d. 30
