5. Distance and center

A park is in the shape of a rectangle. If the endpoints of its two opposite corners are \((-2, 0)\) and \((8, -2)\). Find the distance between them and the center of the park.

 

1. The distance between the opposite corners is $\sqrt{i}$.

 

2. The coordinates of the center of the rectangular park is $\left(i,i\right)$.
