**MathMate**, Sunday, December 5, 2010 at 9:51pmPermimeter is a linear ratio (3:2), and ratio of sides is also a linear ratio (3:2). SO if the shorter is 16, the longer one is 16*3/2=?

**Please Help!**, Sunday, December 5, 2010 at 10:06pmcould I do it in a proportion?

**MathMate**, Sunday, December 5, 2010 at 10:17pmYes, you could do it in proportion as long as both measurements are linear, e.g. perimeter and side.

**Please Help!**, Sunday, December 5, 2010 at 10:26pmI got 10 something but it's not one of the answers

**MathMate**, Sunday, December 5, 2010 at 10:29pm16*3/2 has to be greater than 16, how did you get 10?

**Please Help!**, Sunday, December 5, 2010 at 10:34pm3/2 = .6 repaeating x 16 = 10.6 repeating

and 16/1 x 2/3 = 10.6 reapeating

**MathMate**, Sunday, December 5, 2010 at 10:37pm3/2 = 3 divided by 2 = 1.5

Think of

(16*3)/2 = ?

That should make it easier!

**Please Help!**, Sunday, December 5, 2010 at 10:39pmBut that equals 24 and that not a answer on the thing

**MathMate**, Sunday, December 5, 2010 at 10:42pmSorry, I misread the question (too fast).

The perimeter of the smaller triangle is 16 cm, so the perimeter of the larger triangle should be 24 as you calculated. However, since 24 is the perimeter of three equal sides, each side should measure 24/3=8 cm.

Make sure you understand how it is to be done, or else you will get stuck on the next problem.
