A B 4 units 36 units C Triangle A'B'C' is created by increasing the height of \(\triangle ABC\) by 8 units and applying a scale factor of 0.5 to the base of \(\triangle ABC\). Which statement describing the perimeter of \(\triangle A'B'C'\) is true? A The perimeter of \(\triangle A'B'C'\) is \(18 + 4\sqrt{85}\) units after a proportional dimensional change has been applied to \(\triangle ABC\). B The perimeter of \(\triangle A'B'C'\) is 48 units after a non-proportional dimensional change has been applied to \(\triangle ABC\). C The perimeter of \(\triangle A'B'C'\) is 42 units after a proportional dimensional change has been applied to \(\triangle ABC\). D The perimeter of \(\triangle A'B'C'\) is \(18 + 2\sqrt{1105}\) units after a non-proportional dimensional change has been applied to \(\triangle ABC\).
