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): [tex]\sqrt{25}[/tex] = 5
distance from (-2,1) and (-1,-2): [tex]\sqrt{10}[/tex]
distance from (-1,-2) and (2,4): [tex]\sqrt{45}[/tex] = 3[tex]\sqrt{5}[/tex]
P = 5 + [tex]\sqrt{10}[/tex] + 3[tex]\sqrt{5}[/tex] ≈ 14.9
