If I understand this correctly and graph out the square, then each side equals 6.
This would also mean that a=36 and p=24. Does it sound like I have this right?
The area is 36 square units and the perimeter is 24 units.

Here is another approach, or consider it a way to check instead.
If d = the length of a diagonal of a square, then the number of
square units in that square's area equals \(\displaystyle \ 0.5d^2. \ \ \)
In this case, \(\displaystyle \ 0.5d^2 \ = \ 0.5[(-4 - 2)^2 + (3 - (-3))^2] \ = \)
\(\displaystyle 0.5[(-6)^2 + (6)^2] \ =\)
\(\displaystyle 0.5(36 + 36) \ = \)
\(\displaystyle 0.5(72) \ = \)
\(\displaystyle 36\)
This formula goes directly into squaring the length of a diagonal
of a square and then multiplying that by 0.5.
