Final answer:
The length of line segment XY is 3.2 cm and is dilated with a scale factor of 4 to line segment X'Y'. The length of line segment X'Y' is 12.8 cm.
Step-by-step explanation:
To find the length of line segment X'Y', we can use the proportion method.
Let's set up a proportion using the given information:
X'Y'/XY = Scale factor
Substituting the values:
X'Y'/3.2 = 4
Cross-multiplying:
X'Y' = 3.2 * 4 = 12.8 cm
Therefore, the length of line segment X'Y' is 12.8 cm.
