Question

what is the area of the triangle? 7 km 2 km 5 km square kilometers submit

Explanation:

Step1: Recall the formula for the area of a triangle

The formula for the area of a triangle is \( A = \frac{1}{2} \times \text{base} \times \text{height} \).

Step2: Identify the base and height

From the diagram, the base of the triangle is \( 5 \) km and the height is \( 2 \) km.

Step3: Substitute the values into the formula

Substitute \( \text{base} = 5 \) km and \( \text{height} = 2 \) km into the formula: \( A = \frac{1}{2} \times 5 \times 2 \).

Step4: Calculate the area

First, multiply \( 5 \) and \( 2 \): \( 5 \times 2 = 10 \). Then, multiply by \( \frac{1}{2} \): \( \frac{1}{2} \times 10 = 5 \).

Answer:

\( 5 \)
