Question

what is the length in millimeters of the red line above the metric ruler? (dont forget the unit.)

Explanation:

Step1: Determine the end - point of the red line

The red line starts at \(0.0\) cm. The end - point of the red line is at \(3.3\) cm.

Step2: Convert centimeters to millimeters

Since \(1\) cm \( = 10\) mm, we use the conversion formula \(L(\text{mm})=L(\text{cm})\times10\).
Substitute \(L = 3.3\) cm into the formula: \(L(\text{mm})=3.3\times10\) mm.

Answer:

\(33\) mm
