Question

what is the area of the trapezoid? 3 yd. 6 yd. 7 yd. 7 yd. square yards

Explanation:

Step1: Recall area formula

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

Step2: Identify base and height values

Here, $b_1 = 3$ yd, $b_2=7$ yd and $h = 6$ yd.

Step3: Substitute values into formula

$A=\frac{(3 + 7)\times6}{2}$.
First, calculate the sum in parentheses: $3+7 = 10$. Then, $10\times6=60$, and $\frac{60}{2}=30$.

Answer:

30
