Answer:
Perimeter ⇒ 33 ( units )
Step-by-step explanation:
As you can see, the points share a common y - value, so that they should be positioned with a horizontal distance among them;
[tex]Distance Among Points ( - 9, - 2 ), and ( - 2, - 2 ) , 9 + 2 = 11 units difference,\\[/tex]
Now if the difference is 11 units, we can determine the perimeter of this equilateral Δ assuming the sides are of equal length ( ≅ ) knowing that they do ∈ to an equilateral Δ;
[tex]Side 1 Length - 11 units,\\Side 2 Length - 11 units,\\Side 3 Length - 11 units,\\\\Perimeter = 11 * 3 = 33 units,\\\\Perimeter of Triangle PQR = 33 ( units )[/tex]
Solution; Perimeter ⇒ 33 ( units )
