Answer:
Perimeter is 17.07
Step-by-step explanation:
We know that DF = EF = 5 cm, since D and E are the midpoints of AC and AB, both of which are 10 cm in length.
We need to use the Pythagorean theorem to get the length of DE.

So the perimeter of DEF is 5 + 5 + 7.07 = 17.07
Where the rest of the question?
Answer:
24.38 meters to the nearest hundredth.
Step-by-step explanation:
1 foot is approximately 30.48 cm.
So 80 feet = 80 * 30.48 cm.
In meters this is (80 * 30.48) / 100
= 24.38 m.
