The line must be 5000 meters long, to have an area of one square meter
The question is an illustration of area
The area of a shape is the amount of space occupied by the shape.
From the question, we have the following parameters
[tex]Area =1m^2[/tex]
[tex]Width = 0.2mm[/tex]
Convert the unit from mm to m
[tex]Width = 0.2 \times 0.001 m[/tex]
[tex]Width = 0.0002 m[/tex]
The area is then calculated as:
[tex]Area =Length \times width[/tex]
This gives
[tex]1=Length \times 0.0002[/tex]
Divide both sides by 0.0002
[tex]Length = 5000[/tex]
Hence, the line must be 5000 meters long
