There are two rectangles whose horizontal length is 40 cm.
As shown in Fig. 1, a straight line is drawn toward B from A.
A straight line is drawn for the angle of ① and ②, and the angle of ③ and ④ to become equal, respectively.
(1) In the first rectangle, when writing as ABCDE, E overlapped with A.
Find the vertical length of this rectangle.
(2) In the 2nd rectangle, as shown in Fig. 2, when writing as ABCDEFGHl, the lenghth of A and I was 12 cm. Find the vertical length of this rectangle.
