Question

a. the scale factor from polygon a to polygon b is
← previous

Explanation:

Step1: Identify corresponding sides

The corresponding sides are 2.5 in Polygon A and 5 in Polygon B.

Step2: Calculate scale - factor

The scale factor $k$ is found by dividing the length of a side in Polygon B by the length of the corresponding side in Polygon A. So, $k=\frac{5}{2.5}$.
$k = 2$

Answer:

2
