Answer 2

Answer:

P ≈ 25 units

Step-by-step explanation:

LM = 12 units ( horizontal line )

use the distance formula to find length of other 2 sides.

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = L (- 3, 2) and (x₂, y₂ ) = M (3, 5 )

LM = $\sqrt{3-(-3))^2+(5-2)^2}$

     = $\sqrt{(3+3)^2+3^2}$

     = $\sqrt{6^2+9}$

     = $\sqrt{36+9}$

     = $\sqrt{45}$

Repeat with (x₁, y₁ ) = M (3, 5) and (x₂, y₂ ) = N (9, 2)

MN = $\sqrt{(9-3)^2+(2-5)^2}$

     = $\sqrt{6^2+(-3)^2}$

     = $\sqrt{36+9}$

     = $\sqrt{45}$

Then perimeter P is the sum of the 3 sides

P = 12 + $\sqrt{45}$ + $\sqrt{45}$ = 12 + 2$\sqrt{45}$ ≈ 25 units ( to the nearest unit )
