Answer:
42
Step-by-step explanation:
to find the perimiter youre gonna want to add up all the sides you already have,
so we have 4, 4, 11, and 6.
the reason we dont count the other 4 inside of the figure is because that is inside of it, so we would consider that perimiter
as we see there are other sides not labeled. we have to use that area four to help us.
for the top left side, we do 6 - 4 = 2
for the bottom right side, we do 11 - 4 = 7
then, as we see at the top right we have a four labeled, these look the same width so add a four.
and at the top left, we see another four so add that.
then, add up everything giving you 42.
i hope this helped! <3
