Answer:

10y  mm

Step-by-step explanation:

We would need to know the conversion of cm to mm.

We know

1 cm = 10 mm

If we are given a certain amount of centimeters (cm), to get the answer in millimeters (mm), we multiply that by 10. Example:

1 cm = 10 mm

4 cm would be 4 * 10 = 40 mm

23 cm would be 23 * 10 = 230 mm

Now, we are given "y" centimeters.

So, we multiply by "10" to get the answer in millimeters.

Hence,

y * 10 = 10y millimeters (mm)

The line is 10y mm

Unit of measurement is a measure of quantification. A Metric mode is used for measuring quantities of length, capacity and weight. Centimetre (cm) and millimetre (mm) are the unit of Length used in the Metric system.

For example:

  • 4 cm = 40 mm

  • 6 cm = 60 mm

The correct answer is:

length of the line in millimeters is 10 y

This can be explained as:

Given:

The length of the line = y cm

We know that:

1 cm = 10 mm

  • To convert centimeters to millimeters, multiply the centimeter value by 10.

  • Every centimeter is worth 10 millimeters.

  • ∴ y cm = y x 10 = 10 y mm

Therefore, the length of the line in millimeters is 10 y.
