13. (15 points) The 13th "Maple New Hope Cup" National Mathematics Competition Finals will be held in Hong Kong in August 2017. The competition organizing committee requires the conference staff to hang a banner 14.7 meters long in the conference hall. The banner reads "Maple New Hope Cup National Mathematics Competition Finals Award Ceremony" in 19 large characters. To make the banner aesthetically pleasing, the committee requires that the character width is 4 times the character spacing, and the side space is 5.5 times the character spacing, as shown in the figure:
【Answer】Solution: Let the character spacing be $x$ meters, then $2 \times 5.5 x + 19 \times 4 x + 18 x = 14.7$, solving for $x$ gives $x = 0.14$, margin: $0.14 \times 5.5 = 0.77$ meters, character width: $0.14 \times 4 = 0.56$ meters, answer: The margin, character width, and character spacing are 0.77 meters, 0.56 meters, and 0.14 meters, respectively.
