Question

1. area = ________ 6 8.

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, $b_1 = 3$ in, $b_2=7$ in, and $h = 8$ in.

Step3: Substitute values into formula

$A=\frac{(3 + 7)\times8}{2}$.
First, calculate the sum inside the parentheses: $3+7 = 10$.
Then, multiply by the height: $10\times8=80$.
Finally, divide by 2: $\frac{80}{2}=40$.

Answer:

$40$ in$^2$
