Given: The triangle ABC is provided with DE = 3.2 feet, EF = 4 feet and DF = 2.4 feet.
To find: The perimeter of the triangle ABC.
Step-by-step explanation:
The triangle ABC is given where DE , EF and DF are the midsegments of the triangle ABC.
If DE is the midsegment then using midsegment theorem we have

Since, EF is the midsegment then using midsegment theorem we have

Since, DF is the midsegment then using midsegment theorem we have

We have the sides of the triangle as AB = 8 feet, BC = 6.4 feet and AC = 4.8 feet.
The perimeter of the triangle ABC will be :
P = AB+BC+AC
=8+6.4+4.8
=19.2
Therefore, the perimeter of the triangle is P = 19.2 feet
Final Answer: The perimeter is P = 19.2 feet.
