Answer:
48 cm
Explanation:
First, you may want to find the length of the missing side.
You'll notice that the side across from the missing side is 14 cm. The other side that is across from the 14 cm side (and is parallel to the missing side) is 9 cm. So you would do 14-9 = 5 cm for the missing side.
Then, you just add up all of the side lengths to get the perimeter.
6+10+14+4+9+5 = 48 cm
