Given:
The coordinates of the vertex J is (-6,3) and the coordinates of the vertex L is (5,-2)
We need to determine the length of the diagonal from vertex J to vertex L.
Length of the diagonal:
The length of the diagonal can be determined using the formula,
Substituting the coordinates (-6,3) and (5,-2) in the above formula, we get;
Simplifying, we get;
Thus, the length of the diagonal from vertex J to vertex L is √146 units.
Hence, Option D is the correct answer.
