The problem asks us to determine the length of the line in the image, first in centimeters (cm) and then in millimeters (mm). The line is measured using a ruler.

1. Problem Description

The problem asks us to determine the length of the line in the image, first in centimeters (cm) and then in millimeters (mm). The line is measured using a ruler.

2. Solution Steps

First, observe the start and end point of the line on the ruler.

The line starts at 0 cm and ends at around 9.7 cm. Let's approximate the length to 9.7 cm.

Now, we need to convert the length from centimeters to millimeters. We know the following conversion formula:

$1 \text{ cm} = 10 \text{ mm}$

Therefore, to convert from cm to mm, we multiply by

1

0.

Length in mm = Length in cm * 10

Length in mm = $9.7 \text{ cm} \times 10 = 97 \text{ mm}$

3. Final Answer

a) 9.7 cm

b) 97 mm
