Answer:
38 km
Step-by-step explanation:
1. The formula to find the area of a trapezoid is [tex]\frac{a+b}{2}h[/tex], where a and b are the bases and h is the height.
2. To find the area, all we have to do is plug in these values and simplify!
3. (Solving)
- [tex]\frac{a+b}{2}h[/tex]
- [tex]\frac{4.3+10.9}{2}*5[/tex]
- [tex]\frac{15.2}{2}*5[/tex]
- [tex]\frac{76}{2}[/tex]
- [tex]38[/tex]
Therefore, the area is 38 km.
