Answer 1

9, 15, 22.
If you add any of the two side lengths, they will be greater than the third.

Answer 2

9 cm,15 cm and 22 cm could be length of sides of a triangle.

Explanation:

If a,b and c are the length of the sides of a triangle then,

a<b+c, b<a+c and c<b+a

Let a=9 cm

b=15 cm

and c=22 cm

9<15+22 , 15<9+22 and 22<15+9

Hence, 9 cm,15 cm and 22 cm could be length of sides of a triangle.
