Question

these two polygons are similar. w = ?

Explanation:

Step1: Find the scale - factor

The ratio of corresponding sides of similar polygons is the same. Let's take the ratio of two known corresponding sides. For example, $\frac{9}{3}=3$.

Step2: Calculate the value of $w$

Since the scale - factor is 3 and the corresponding side of $w$ in the small polygon is 2, then $w = 2\times3$.
