Answer:
2.5in
Step-by-step explanation:
Given parameters;
Base = 4.5inches
Height = 6inches
Area = 21in²
Unknown:
b₂ = ?
Solution:
Formula for finding the area of a trapezium;
A = x h
Input the parameters and solve for b₂;
21 = x 6
21 = 3(4.5 + b₂)
21 = 13.5 + 3b₂
21 - 13.5 = 3b₂
b₂ = 2.5in

The question is incomplete as options are not given. However, a general explanation is as follows:
Rewrite
When a = 0
When a = 1
This means that:
For
Then
<em>This means that: b is a number between 0 and 8</em>
