Answer:

  4

Step-by-step explanation:

If all were measure 5, the perimeter would be 30. The perimeter is 4 more than that. Each side that is 6 instead of 5 adds 1 to the perimeter, so there are 4 sides of length 6.

Answer:

4

Step-by-step explanation:

If all sides measured $6$ units, the total perimeter would be $36$. But this is $2$ too many units, so we must change two of these sides to $5$ units. Thus $\boxed{4}$ sides measure $6$ units.
