Question

5 multiple choice 5 points find the area of this triangle. 9 20 18 80

Explanation:

Step1: Recall the area formula for a right - triangle

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

Step2: Identify the base and height

In the given right - triangle, the base \(b = 4\) and the height \(h=10\).

Step3: Substitute values into the formula

Substitute \(b = 4\) and \(h = 10\) into \(A=\frac{1}{2}\times b\times h\). We get \(A=\frac{1}{2}\times4\times10\).

Step4: Calculate the area

First, \(4\times10 = 40\), then \(\frac{1}{2}\times40=20\).

Answer:
