Question

1. find the area of this triangle. multiply the base and the height and divide the total by 2.

Explanation:

Step1: Apply the area formula for a triangle

The formula for the area of a triangle is \(A=\frac{1}{2}\times b\times h\), where \(b\) is the base and \(h\) is the height. Here, \(b = 30\) km and \(h=17\) km.

Step2: Substitute the values into the formula

\(A=\frac{1}{2}\times30\times17\)
First, calculate \(30\times17 = 510\).
Then, \(\frac{1}{2}\times510=255\)

Answer:

\(255\) km²
