Triangle DEF is formed by connecting the midpoints of the sides of triangle ABC. What is the perimeter of
triangle ABC?
​

18

Step-by-step explanation:

Mathematically, the side lengths of ABC is twice that of DEF

so we have side lengths of ABC as;

2(2) , 2(3) and 2(4)

= 4, 6, 8

The perimeter is thus, the addition of the side lengths

4 + 6 + 8 = 18

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn
