Question

what is the area, in square feet, of the trapezoid below? answer attempt 1 out of 100 $a=square$ $ft^{2}$

Explanation:

Step1: Recall area formula

$A=\frac{1}{2}(b_1 + b_2)h$, where $b_1$ and $b_2$ are bases and $h$ is height.

Step2: Identify values

$b_1 = 5$ ft, $b_2=8.1$ ft, $h = 5$ ft.

Step3: Substitute values

$A=\frac{1}{2}(5 + 8.1)\times5$.

Step4: Calculate sum in parentheses

$5+8.1 = 13.1$.

Step5: Multiply by $\frac{1}{2}$ and 5

$A=\frac{1}{2}\times13.1\times5=32.75$ ft².

Answer:

$32.75$
