Hello!
To find the area of a trapezoid you use the equation
![A = \frac{a+b}{2} h](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cfrac%7Ba%2Bb%7D%7B2%7D%20h)
Put in the values you know
![390 = \frac{23+29}{2} h](https://tex.z-dn.net/?f=390%20%3D%20%20%5Cfrac%7B23%2B29%7D%7B2%7D%20h)
Add
![390 = \frac{52}{2} h](https://tex.z-dn.net/?f=390%20%3D%20%5Cfrac%7B52%7D%7B2%7D%20h)
Divide
![390 = 26 * h](https://tex.z-dn.net/?f=390%20%3D%2026%20%2A%20h)
Divide both sides by 26
15 = h
The answer is 15km
Hope this helps!
