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)
