In this case, we'll have to carry out several steps to find the solution.
Step 01:
similar triangles:
side ratio = 7:5
ratio perimeter = ?
Step 02:
Similar triangles:
Triangle 1:
perimeter T1 = s1 + s2 + s3
Triangle 2:
perimeter T2 = s1 + s2 + s3
7:5 ratio
7 * perimeter T1 = 5 * perimeter T2
The answer is:
In two similar triangles: the perimeters of the two triangles are in the same ratio as the sides.
7 : 5
