Answer:
38.64 km^2
Step-by-step explanation:
The formula for the area of a trapezoid is:
[tex]\frac{(b_{1}+b_{2})*h}{2}[/tex]
Where b1 and b2 are the bases and h is the height. We are given 2.9 and 10.9 as the bases and 5.6 as the height. We can plug these values into the formula:
[tex]\frac{(2.9+10.9)*5.6}{2}[/tex]
After entering the expression in the calculator, you get:
38.64 km^2
This is the first option.
