Here is Quadrilateral . Quadrilateral ABCD is on a grid. Point a is 2 units right and 4 units down from the edge of the grid. Point B is 2 units right and 2 units up from point A. Point C is 6 units right from point A. Point D is 2 units right and 4 units down from point A. Quadrilateral is a scaled copy of Quadrilateral . Point corresponds to , to , to , and to . If the distance from to is 3 units, what is the distance from to ? Explain your reasoning.
