Look at triangle abc.
what is the length of side ab of the triangle?
3
5
square root of 6
square root of 13

Option D is correct.

The length of AB = units.

Explanation:

Use Distance(D) formula for two points (x_1 ,y_1) and (x_2 ,y_2) is given by:

From the given figure in triangle ABC, A =(4,5) and B= (2,2),

then by using distance formula, we have;

AB =

AB= or

AB=

or

AB= =

Therefore, the length of AB = unit.
