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

Step-by-step explanation:
100 = ( 8 + 2x) ( 10 + 2x )
100 = 80 + 36x + 4x ^2 ( binomial product )
80 + 36x + 4x^2 = 100
80 + 36x + 4×^2 - 100 = 100 - 100
4x^2 + 36x - 20 = 0
