Milimeters: Well the questions says "The perimeter of a triangle is 16cm(160mm) .What is the missing measurement?(picture in my math book)Record your work on your journal blog,the measurement in cm and mm. (This is not an equalateral triangle).One side is 41 mm(4.1cm).Another side is 5cm(50mm).So all I did was add 41mm+50mm(which is 91mm)(9.1cm)and then subtracted 160mm(16 cm)from 91mm(which is 69mm).So then I found out that the missing measurement was 69mm.
Centimeters:Well I did the same thning a s the milimeters but in centimeters so one side was 4.1cm(41mm),another was,5cm and I added those two together to get 9.1 and subtracted that from 16cm (which is 6.9cm). So add 6.9cm with 4.1cm and 5cm and you get 16 centimers.
