Perimeter is measured in centimeters (or inches, or feet). meters squared, or inches squared or feet squared is area. 

Do you mean area or perimeter for this problem?

I'm sorry I'm still not clear on what you're looking for.  Is it area or perimeter?

perimeter

ok.  :) 

"Perimeter" means "how long is the border?"

First some unit conversions ==>  4cm = 40mm
