Question

what is the area of the trapezoid? 1.1 km 1.5 km 1.2 km 1.5 km 2.9 km square kilometers

Explanation:

Step1: Recall area formula

The area formula for a trapezoid is $A=\frac{(b_1 + b_2)h}{2}$, where $b_1$ and $b_2$ are the lengths of the bases and $h$ is the height.

Step2: Identify base and height values

Here, $b_1 = 1.1$ km, $b_2=2.9$ km and $h = 1.2$ km.

Step3: Substitute values into formula

$A=\frac{(1.1 + 2.9)\times1.2}{2}=\frac{4\times1.2}{2}$.

Step4: Calculate the result

$\frac{4\times1.2}{2}=\frac{4.8}{2}=2.4$ square - kilometers.

Answer:

2.4
