Recall that the perimeters of similar triangles are proportional to the scale factor between them.

Practice makes perfect
Let's begin with recalling what we know about the perimeters of similar polygons.
If two polygons are similar, then their
perimeters are proportional to the scale factor between them.We can use this information and create a proportion.
Perimeter_1/Perimeter_2=Side_1/Side_2
By substituting 53.5 and 32.1 for the perimeters and 25 for the side length of the first garden, we can evaluate the side length of the second garden. Let x be this length.
