Answer:
Explanation:
To find the percent of change from 12 inches to 36 inches, we can use the following formula:
percent change = (new value - old value) / old value x 100%
Using this formula, we can substitute the values:
percent change = (36 - 12) / 12 x 100%
percent change = 24 / 12 x 100%
percent change = 200%
Therefore, the percent of change from 12 inches to 36 inches is 200%. This means that the value increased by 200% or tripled in size.
