Answer 1
thickness
This answer is not correct. One meter is about the length of a persons arm. No door would
be 1 m thick with the possible exception of a bank vault. return to top
Answer 2
width
This answer is correct! The width of a door is about 1 meter (nearly the length of your
arm). return to top
Answer 3
height
This answer is incorrect! most doors are more like 2 meters tall. Only small children
would find it comfortable to walk through a 1 meter tall doorway. return to

length. This would be measured in square meters or square centimeters. return

What's this question really asking?
This question is asking whether you understand what the length of 1 meter is. They are
asking you to compare this to something you would find every day...a door.
