Above are two different models of the same pentagon. If the length of side b is 28 cm, what is the length of side a?
To determine the length of side a, we can use the properties of similar polygons.
In the first model, we can see that side a is double the length of side b. Therefore, side a = 2 * 28 cm = 56 cm.
In the second model, we can see that side a is three times the length of side b. Therefore, side a = 3 * 28 cm = 84 cm.
So, depending on which model we are looking at, the length of side a can be either 56 cm or 84 cm.
