The side length is 16 cm
The area of a square is
A = s^2
A = 16^2
A =256 cm^2

Answer:
25%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
Here, new number = 30, and old number = 24.
percent change = (30 - 24)/(24) * 100%
percent change = 6/24 * 100%
percent change = 0.25 * 100%
percent change = 25%
