Answer:
___________________________________________________
The answer choices:
_______________________________________
[C]: " 12.5 m " ;
______________________
[E]: " 17.5 m " ;
______________________
[F]: " 20 m " ;
_____________________________________________
are the correct answer choices; as explained below.
__________________________________________________
Step-by-step explanation:
________________________________________________
How to solve:
_____________________________________________
We are given the length of EACH of the 3 (THREE) sides of the triangle.
Note that EACH length given (on each side of the triangle in the figure) is in units of "mm" ("meters"). Note that ALL of the answer choices given are in units of "m" ("meters").
____________________________________________________
Take the "number" (in "mm" of the length of EACH side of the triangle—but ignore the units of "mm"); divide that number by 24; and then multiply [this obtained value] by "5 m". Do this for the EACH side length of the triangle in the figure. Any answer you have for any of these values that appears as an answer choice given is a correct answer.
__________________________________________________
So, start with:

1) side length: "96 mm" . 96/24 = 4.
4 * 5 m = 20 m ; which is: "Answer choice: [F]" .
__________________________________________________
2) side length: "60 mm". 60/24 = (60÷12)/(24÷12) = 5/2 = 2.5 .
2.5 * 5 m = 12.5 m ; which is: "Answer choice: [C]" .
__________________________________________________
3) side length: "84 mm". 84/24 = 3.5 .
3.5 * 5 m = 17.5 m ; which is: "Answer choice: [E]".
______________________________________________________
So the answers are:
______________________________________________________
Answer choices: [C], [E], and [F] are correct.
