Answer 1

Answer:

P = 14.9

Step-by-step explanation:

i used distance formula:  

d = √(difference of y-values, squared, + difference of x-values, squared)

distance from (-2,1) and (2,4):  $\sqrt{25}$ = 5

distance from (-2,1) and (-1,-2):  $\sqrt{10}$

distance from (-1,-2) and (2,4):  $\sqrt{45}$ = 3$\sqrt{5}$

P = 5 + $\sqrt{10}$ + 3$\sqrt{5}$  ≈  14.9
