Kim wants to put new baseboards on the walls of the room. If the scale is 2 cm:1 m and the baseboard costs $4.19 per meter, how much would it cost to put baseboards in Kim’s living room?

Thank you for the opportunity to help you with your question!

 the scale is 2cm: 1m     ;    100cm= 1m

rewriting it in same units of measure = 2cm : 100cm   = 1:50

The cost will be  1 *4.19/50 =  $ 0.0838

Please let me know if you need any clarification. I'm always happy to answer your questions.
