Question

Arrange the following units of length from the largest to the smallest value.

• A. Metre (m)
• B. Millimetre (mm)
• C. Kilometre (km)
• D. Centimetre (cm)

Answer 1

The units of length can be related as follows:

$1km=1000m$.
$1m=100cm$.
$1cm=10mm$.

Representing the relation in form of a diagram,

$km$ to $m$ can be represented as:

$m$ to $cm$ can be represented as:

$km,mandcm$ can be represented as:


Hence, the units of length arranged from the largest to the smallest value is:

$Kilometre\left(km\right)$
$Metre\left(m\right)$
$Centimetre\left(cm\right)$
$Millimetre\left(mm\right)$
