Answer:
16.12 mi²
Explanation:
The formula for the area of a trapezoid is A = 1/2h(
), where
stands for base 1, and
represents base 2. Plugging in the given values, we have A = 1/2(3.1)(8.3 + 2.1). Now we can solve.
------------------------------
A = 1/2(3.1)(8.3 + 2.1)
1/2(3.1)(10.4)
1.55(10.4)
= 16.12 mi²
hope this helps!
