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!!
