Answer:

3cm < L < 15cm

Step-by-step explanation:

Given :

Side lengths:

Side 1 = 6cm and side 2 = 9cm

In other to construct a valid triangle, the length of the third side must lie in between.

That is ;

Minimum length must be greater than :

(side 2 - side 1)

9cm - 6cm = 3cm

Maximum length must not exceed :

(side 1 + side 2)

9cm + 6cm = 15cm

Hence, for a valid length for the 3rd side, L:

L > 3cm and L < 15 cm

3cm < L < 15cm
