Question

what is the area of the trapezoid? square miles

Explanation:

Step1: Recall 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 bases and $h$ is the height.

Step2: Identify values

Here, $b_1 = 2$ mi, $b_2=5$ mi, and $h = 2$ mi.

Step3: Substitute values

$A=\frac{(2 + 5)\times2}{2}$.

Step4: Simplify

First, calculate inside the parentheses: $2+5 = 7$. Then, $A=\frac{7\times2}{2}=7$.

Answer:

7
