Explanation:
To find the area of a trapezoid, use this equation:
![A = (a+b)/(2)h](https://img.qammunity.org/2023/formulas/mathematics/middle-school/ckthkgcdvohdqwfncthyl9suuzsmrigksl.png)
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:
![A = (4+10)/(2) (12)](https://img.qammunity.org/2023/formulas/mathematics/middle-school/gjmv8igi8kqmwtnegzeh3kkn5w5d4weaul.png)
Add what's in the numerator
Divide 14 by 2
A = 84
Multiply 7 by 12
So, the area of the trapezoid is 84
.
Hope this helps!!
