After plotting the points in a cartesian plane, it is noted that there resemble endpoints of a parallelogram. One pair of sides measures 3 units long. This is obtained by subtracting 3, the y - intercept of (3, 3) from 6, the y - intercept of (3, 6). Alternatively, this can also be obtained by using the other two points.
The second pair of side measures approximately 4.90 units long. This is solved through the Pythagorean theorem.
