For three sides shouldn't there be another number in the ratio?
OpenStudy (anonymous):
I'm guessing it means 3:6 so it's 3 on each side and 6 on the third.
OpenStudy (anonymous):
Yes its 19 the missing one
OpenStudy (anonymous):
Oh. Then it's just 3, 6 and 19 cm for the lengths of the triangle. Adding those up is 28.
