Answer 2

Answer:

Step-by-step explanation:

length of the pieces= 0.2km,5005cm,1200mm

hence convert all of them in m since at the end of the question it says per meter. So, it will be easy if we convert it right now into meters.

• 0.2 km=200m
• 5005cm=50.05m

• 002mm=0.0012m

now add them:

=250.0512m
