Answer:
169 mi²
Step-by-step explanation:
To find the area of a trapezoid, use this formula:
[tex]A=\frac{a+b}{2} h[/tex]
"a" and "b" represent the two bases (12 mi and 14 mi), and the "h" stands for height (13 mi). Insert these values into the equation.
[tex]A=\frac{12+14}{2} 13[/tex]
[tex]A=\frac{26}{2} 13[/tex]
[tex]A=13 * 13\\= 169[/tex]
Therefore, A = 169. :)
