Answer:
Height = 5 ft
Short base = 10 ft
Long base = 14 ft
Step-by-step explanation:
Let h = height, a = short base, b = long base.
From the question,
a = 2h
b = a + 4 = 2h + 4
The area of the trapezoid is given by
. Thus,







or 
or 
We discard the negative value of h since it is a measurement and cannot be negative.

Simplifying
34 = 10 + 4q
Solving
34 = 10 + 4q
Solving for variable 'q'.
Move all terms containing q to the left, all other terms to the right.
Add '-4q' to each side of the equation.
34 + -4q = 10 + 4q + -4q
Combine like terms: 4q + -4q = 0
34 + -4q = 10 + 0
34 + -4q = 10
Add '-34' to each side of the equation.
34 + -34 + -4q = 10 + -34
Combine like terms: 34 + -34 = 0
0 + -4q = 10 + -34
-4q = 10 + -34
Combine like terms: 10 + -34 = -24
-4q = -24
Divide each side by '-4'.
q = 6
Simplifying
q = 6
