Question

The triangles at the right are similar. What is the ratio (larger to smaller ) of the perimeters ?

Answer 1

The perimeters are in the same ratio as the corresponding sides.

Explanation:

There is no diagram given in your question, so imagine an example in which the ratio of two corresponding sides is, say, 7:4 (or 7/4). Then the perimeters are in the same ratio, 7:4.

Note: The areas are in the ratio which is the square of the ratio of sides, so 49:16 in the example.
