Answer:

In question 3 a triangle can be formed however in question 4 it can't be formed

Explanation:

there is a theorem that states that two sides of a triangle when added up should be greater than the third one which isn't true in question 4 as

12+9=21 so its equal to the third side but not greater hence a triangle can't be formed
