The distance between two consecutive points determines the length of each side of the rectangle.
The distance between (-7,-2) and (-3,-2) is 4 units (horizontally).
The distance between (-7,-2) and (-7,-5) is 3 units (vertically).
Therefore, the perimeter is 4 + 3 + 4 + 3 = 14 units.
So, the correct answer is:
3. 14 units
