Answer:
1200 millimeters
Step-by-step explanation:
Given
Height=1 meter 20 centimeter
In order to convert the height into millimeter we have to convert to millimeter
We will have to convert the meters into centimeters and then centimeters into millimeter.
So,
We know that
1 meter=100 cm
So total height in centimeters will be:
1 meter 20 centimeter=100+20
= 120 cm
In order to convert centimeters into millimeters, we will use
1 cm=10 millimeter
To convert into smaller unit, multiplication is used,
So,
120 cm=120*10
=1200 mm
So the height in millimeter is 1200 ..
