The sides of a hexagon are 4,3,4,6,8, and 9. find the perimeter of a similar hexagon with two sides of length 3.

If two shapes are similar, it means that you can obtain one from the other by scaling it by a certain factor (you can think of this as of "zooming" the shape in or out).

In particular, this implies that all the side lengths are multiplied by the same amount.

Now, the original hexagon has two sides of 4, and all other sides are different. This implies that, if we multiply all side lengths by the same number, we will still have two sides with equal lengths, and all other sides will have different lengths.

So, the 2 sides with length 3 must come from the two sides with length 4, after scaling. In particular, this also implies that the scaling factor is

So, the perimeter of the new hexagon is the sum of its sides, which in turn are the old sides multiplied by the scaling coefficient:
