Question

what is the area of the triangle? triangle with base 3 km, height 2 km, and one side 3 km square kilometers

Explanation:

Step1: Recall triangle area formula

The formula for the area of a triangle is $\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$

Step2: Substitute given values

Here, base $= 3$ km, height $= 2$ km. Substitute into the formula:
$\text{Area} = \frac{1}{2} \times 3 \times 2$

Step3: Calculate the result

Simplify the expression: $\frac{1}{2} \times 6 = 3$

Answer:

3 square kilometers
