I need the correct answer for the: Centroid cluster A, Centroid cluster B, The IV, and the EV

Thank you

For the K-means clustering algorithm, the quality of clusters can be evaluated by V and EV. In the following figure blue points belong to Cluster A and red points belong to Cluster B. If you results include square root 2 , you can use sqrt(2) to represent it. If you results include square root 3 , you can use sqrt(3) to represent it. If you results include square root 5 , you can use sqrt(5) to represent it. Centroid of cluster A is: Centroid of cluster B is: The VV is: The EV is
