Answer:

your answer is correct.. its 10

Step-by-step explanation:

  1. you got to look at the length of each line
  2. observe the distance between each letter and calculate your answer

as you can see the line DC and EF are the same exact length.

CM =5

line CM is half of line DC. which means to fine the length of EF you must multiply 5 by 2 (5×2) to get the length of EF which is 10

hope this helps
