Answer: 9 cm

You can figure this out because the unknown side combined with the 5cm side is equal to the 14cm side. Therefore, subtract 5 from 14 to find out the unknown side.

The missing side is 9cm

The perimeter is 44cm

Explanation:

To find the missing side you subtract 5 from 14 since the missing side added to 5 would have the length of 14.
So, 14-5 = 9

The perimeter is calculated by adding all sides:
14 +8+5+3+9+5= 44
