One side of a triangle cannot be more than the sum of the other two sides. Thus, if the two sides of the triangle are equal respectively:

a) 7 cm and 16 cm, then the third side must be less than 7 + 16 = 23 (cm);

b) 21 cm 7 mm and 47 cm 6 mm, then the third side should be less than 21.7 + 47.6 = 69.3 (cm);

c) 5 cm and 12 cm, then the third side should be less than 5 + 12 = 17 (cm);

d) 2 cm 3 mm and 7 cm 8 mm, then the third side should be less than 2.3 + 7.8 = 10.1 (cm).

Answer: a) <23 cm; b) <69.3 cm; c) <17 cm; d) <10.1 cm.
