Question

Explanation:

Step1: Understand number types

Exact numbers are counts or defined values (e.g., 2 apples, 1 meter = 100 cm). Measured numbers come from measurements (with uncertainty, e.g., length of a laceration measured as 4 cm).

Step2: Analyze the 4 cm laceration

The 4 cm is a measurement of the laceration's length, obtained via a measuring tool (like a ruler), so it's a measured number.

Answer:

Measured (the option: "Measured")
