Help me out with this math problem for 50 points!!!

Answer:
A = 84 [tex]ft^{3}[/tex]
Step-by-step explanation:
To find the area of a trapezoid, use this equation:
[tex]A = \frac{a+b}{2}h[/tex]
a = top base
b = bottom base
h = height
Let's classify all the sides:
a = 4 ft
b = 10 ft
h = 12 ft
Now, let's plug all these into the equation:
[tex]A = \frac{4+10}{2} (12)[/tex]
[tex]A = \frac{14}{2}(12)[/tex] Add what's in the numerator
[tex]A = 7(12)[/tex] Divide 14 by 2
A = 84 [tex]ft^{3}[/tex] Multiply 7 by 12
So, the area of the trapezoid is 84 [tex]ft^{3}[/tex].
Hope this helps!!
