Answer:
7 + k years old
Explanation:
If k years ago, Ella was 5 years old, it means she is currently 5 + k years old.
To find out how old she will be in 2 years, we need to add 2 to her current age:
Ella's age in 2 years = 5 + k + 2
Ella's age in 2 years = 7 + k years
So, Ella will be 7 + k years old in 2 years.
