To compute the perimeter of a parallelogram, we need to know the lengths of two adjacent sides. The formula for the perimeter \( P \) of a parallelogram given side lengths \( a \) and \( b \) is:
\[ P = 2(a + b) \]
If you provide the coordinates of the vertices of the parallelogram, I can help calculate the lengths of the sides using the distance formula:
\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]
Once we determine the lengths of the two sides, we can then compute the perimeter accordingly.
Please provide the specific coordinates of the vertices of the parallelogram so I can assist you further!
