Question

what is the area of the trapezoid? 0.3 km 0.5 km 0.6 km 0.7 km square kilometers

Explanation:

Step1: Recall area formula

The area formula for 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

Here, $a = 0.3$ km, $b = 0.7$ km, and $h = 0.5$ km.

Step3: Substitute values into formula

$A=\frac{(0.3 + 0.7)\times0.5}{2}$.
First, calculate the sum inside the parentheses: $0.3+0.7 = 1$.
Then, multiply by the height: $1\times0.5 = 0.5$.
Finally, divide by 2: $A=\frac{0.5}{2}=0.25$ square kilometers.

Answer:

$0.25$
