Quadrilateral LMPQ is shown on the coordinate grid. Quadrilateral LMPQ will be dilated to create Quadrilateral L'M'P'Q'. Quadrilateral LMPQ will be dilated with the origin as the center of dilation using the rule (x,y) --> (3.75x, 3.75y). Which statement is true?

• Each angle measure of quadrilateral L'M'P'Q' will be 3.75 times the corresponding Angle measure of quadrilateral LMPQ.

• Each angle measure of quadrilateral L'M'P'Q' will be 3.75 more than the corresponding angle measure of quadrilateral LMPQ.

• Each side length of quadrilateral L'M'P'Q' will be 3.75 times the corresponding side length of the quadrilateral LMPQ.

• Each side length of quadrilateral L'M'P'Q' will be 3.75 more than the corresponding side length of quadrilateral LMPQ.
