• 4.5 cm

Answer 1

In a triangle the lengths of two sides are 4 cm, 8 cm. ∴ The third side can be 4.5 cm.

Explanation:

In any triangle,

Difference of two sides < Third side < Sum of two sides

For sides 4 cm and 8 cm:

Difference = 8 − 4 = 4

Sum = 8 = 4 = 12

So, 4 < Third side < 12

The third side can be 4.5 cm.
