Question

1. from 12 ft to 23 ft % increase decrease

Explanation:

Step1: Determine the change amount

First, find the difference between the new value and the original value. The original value is 12 ft and the new value is 23 ft. So the change amount is \( 23 - 12 = 11 \) ft.

Step2: Calculate the percentage increase

The formula for percentage increase is \( \frac{\text{Change Amount}}{\text{Original Amount}} \times 100\% \). Substituting the values, we get \( \frac{11}{12} \times 100\% \approx 91.67\% \). Also, since 23 > 12, it's an increase, so we select the "Increase" option.

Answer:

The percentage change is approximately 91.67% and it is an Increase. So fill in 91.67 (or similar decimal approximation) and select Increase.
