Question

what is the area of the trapezoid? 4 km 5 km 3 km 5 km 12 km square kilometers

Explanation:

Step1: Recall area - formula for trapezoid

The formula for the area of a trapezoid is $A=\frac{(a + b)h}{2}$, where $a$ and $b$ are the lengths of the parallel sides and $h$ is the height.

Step2: Identify values of $a$, $b$, and $h$

Here, $a = 4$ km, $b = 12$ km, and $h=3$ km.

Step3: Substitute values into the formula

$A=\frac{(4 + 12)\times3}{2}=\frac{16\times3}{2}$.

Step4: Calculate the result

$\frac{16\times3}{2}=\frac{48}{2}=24$ square kilometers.
