Possible lengths of the three sides of a triangle are :

1. 2 cm, 3 cm and 6 cm
2. 3 cm, 4 cm and 5 cm
3. 2.5 cm, 3.5 cm and 6 cm
4. 4 cm, 4 cm and 9 cm

Correct Option: B

We know that the sum of two sides of a triangle is greater than the third side.
Clearly,
3 + 4 > 5
4 + 5 > 3
5 + 3 > 4
Therefore , Possible lengths of the three sides of a triangle are 3 cm, 4 cm and 5 cm .
