Answer:
The answer to your question is 19.2 feet.
Step-by-step explanation:
With the data given, we can see that we have a right triangle in the middle of the bigger one. Also, we can see that we have four triangles inside the biggest one, and all these triangles have the same size.
Then we can know the length of the three sides of:
BC = DE + DE = 3.2 + 3.2 = 6.4
AB = EF + EF = 4 + 4 = 8
AC = DF + DF = 2.4 + 2.4 = 4.8
Perimeter = BC + AB + AC = 6.4 + 8 + 4.8 = 19.2 feet
