Answer:
4/3
Explanation:
To find the scale factor from figure 1 to figure 2, divide a length in figure 2 by its corresponding length in figure 1.
Both legs of figure 1 measure 3 units.
Both legs of figure 2 measure 4 units.
Each leg measuring 3 units corresponds to a leg measuring 4.
scale factor = (length in figure 2)/(corresponding length in figure 1)
scale factor = 4/3
Check:
The way a scale factor works is that when you multiply a length in figure 1 by the scale factor, you get the corresponding length in figure 2.
figure 1 length: 3
scale factor: 4/3
product: 3 × 4/3 = 12/3 = 4
Yes, we do the correct length in figure 2, so our scale factor of 4/3 is correct.
