.
In triangle CDE, the side DE is 13 cm long, and the side CE is 12 cm long.


They want you find the length of the side CD.


Apply the triangle inequality.


According to the triangle inequality,  CD is shorter than the sum  12 + 13 = 25 cm  and longer than the difference 13 - 12 = 1 cm.


ANSWER.  The length of the side CD is longer than 1 cm and shorter than 25 cm.
