Find the perimeter of the parallelogram. (please answer asap! ty!)

Perimeter of the parallelogram is 20 units.According to question,3 + x = 2a - 4      x = 2a - 4 - 3     x = 2a - 7Diagonals in a parallelogram bisects each other.Therefore, 2a - 7 = 3                        2a = 3 + 7                        2a = 10                           a = 10/2                           a = 5a - 1 = 4b - 65 - 1 = 4b - 6     4 = 4b - 6   4b = 4 + 6    4b = 10      b = 10/4      b = 5/2Opposite sides of a parallelogram are equal.Therefore, c - 2 = 2b                   c - 2 = 2(5/2)                   c - 2 = 5                        c = 5 + 2                        c = 7Sides of parallelogram,Side 1 = 12 - c           = 12 - 7           = 5Side 2 = c - 2            = 7 - 2            = 5Perimeter of parallelogram = 2(length of side 1 + length of side 2)                                              = 2(5 + 5)                                              = 2 * 10                                              = 20Hence, perimeter is 20 units.To learn more about Perimeter here:https://brainly.com/question/6465134#SPJ1
