Rosy measured a line for his art project. It is $400$ millimeters long. How many centimeters is the line?
$0.4$ cm
$40$ cm
$4$ cm
$400$ cm

The total length of the line is $400$ mm.
We know that $1$ $centimeter = 10$ $millimeters$
$1$ mm $= \frac{1}{10}$ cm
We have to convert the $400$ mm to cm.
$400$ mm $= \frac{1}{10} \times 400$ cm
$= \frac{400}{10}$ cm
$= 40$ $centimeter$
The line is $40$ cm long.
So, option A is correct.
