$A_"Trapezoid"=1/2(b_"1"+b_"2")h$

This is always the formula for solving the area of a trapezoid, where $b_"1"$ is base 1 and $b_"2"$ is base 2.

If we were to solve for the area of this trapezoid, it would be

$A=1/2(8+6)4$
$A=1/2(14)4$
$A=7*4$
$A=28"units"^2$ Remember that area units are always squared

You may also see it written as

$A=(a+b)/2 * h$ , which is still the same thing

Sidenote: You may have noticed that the $7$ and $5$ became negligible when solving the area, as these will never be used for area of a trapezoid.
