Answer:
112ft
Explanation:
The length of the little rectangle jutting out is the only unmarked length, so once we find that we can just add up all the sides to find the perimeter.
We see the overall length of the shape is 24ft and the length of the top of the shape, minus the unmarked length, is 16ft. This means the unmarked length is 24ft-16ft=8ft
Now add up each side to get to the perimeter:
32ft + 16ft + 16ft + 8ft +8ft +8ft +8ft +16ft = 112ft
