deff fn [24]

Answer:

24.4 Units

Step-by-step explanation:

For this, we will use the distance formula to find the distance between each vertex

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

So we do this for each side of the triangle to get AB = $\sqrt{52}$ , BC = $\sqrt{109}$ , and AC = $\sqrt{45}$

We add these all up to get 24.4 (rounded)
