Question

1. find the area. area = ____ in²

Explanation:

Step1: Recall trapezoid area formula

The formula for the area of a trapezoid is $A=\frac{(b_1 + b_2)h}{2}$, where $b_1$ and $b_2$ are the lengths of the parallel - sides and $h$ is the height.

Step2: Identify values

Here, $b_1 = 6$ in, $b_2=12$ in, and $h = 5$ in.

Step3: Substitute values into formula

$A=\frac{(6 + 12)\times5}{2}=\frac{18\times5}{2}$.

Step4: Calculate

$\frac{18\times5}{2}=\frac{90}{2}=45$ in².

Answer:

45
