Final answer:
The student is seeking to find the scale factor between the perimeters of two polygons. The scale factor is the ratio of the corresponding sides of similar figures. Specific perimeters are not provided to calculate an exact scale factor.
Step-by-step explanation:
The student is asking to find the scale factor between the perimeters of two polygons, ABDCE and RSTUV. The scale factor is a ratio that describes how the size of one object relates to another. To find it, you would typically divide the perimeter of one figure by the perimeter of the other figure, assuming that the two figures are similar and the corresponding sides are proportional.
Since the actual dimensions or perimeters of the polygons in question are not provided in the student's question, I cannot give a specific numerical answer. However, the general approach to finding the scale factor when given two perimeters is to set up a ratio. For example, if the perimeter of ABDCE were 10 units and the perimeter of RSTUV were 20 units, the scale factor from ABDCE to RSTUV would be 1:2.
If the question had included specific values for the perimeters, we would use a proportion to calculate the scale factor:
scale factor = perimeter of ABDCE / perimeter of RSTUV
This mirrors the method used in the examples provided, where a proportion is set up to find the missing actual dimension when given a scale and a measurement.
