Answer:
Total length of Precambrian period is [tex]6[/tex] meter [tex]45[/tex] centimetres
Explanation:
Precambrian period has two major sub divisions
a) Archean (oldest) and
b) Proterozoic
The length of Precambrian period would be equal to the sum of length of Archaean eon and the Proterozoic eon.
The length of Proterozoic eon [tex]= 240 + 55\\[/tex]
[tex]= 295[/tex]
Or
[tex]2[/tex] meter [tex]95[/tex] centimetres
The length of Archean eon [tex]= 3[/tex] meter [tex]50[/tex] cm
Total length of Precambrian period [tex]= 295 + 350\\[/tex]
[tex]= 645[/tex] centimetres
Or
[tex]6[/tex] meter [tex]45[/tex] centimetres
