Question

the figures shown are similar. find the scale factor from the smaller figure to the larger figure and enter in the red box below. scale factor is smaller figure to larger. enter a:b 7 4 12 12 21

Explanation:

Step1: Identify corresponding sides

The smaller rectangle has sides 4 and 7, the larger has 12 and 21. Take corresponding sides (e.g., 4 and 12, or 7 and 21).

Step2: Calculate scale factor (smaller to larger)

Scale factor = larger side / smaller side. Using 4 and 12: $\frac{12}{4} = 3$ (or $\frac{21}{7} = 3$).
