Explanation:

Step1: Recall the formula for the area of a right - triangle

The formula for the area of a right - triangle is \(A=\frac{1}{2}\times base\times height\). In a right - triangle, the two legs can be considered as the base and the height. Here, the legs are \(b = 3\) and \(h=4\).

Step2: Substitute the values into the formula

Substitute \(b = 3\) and \(h = 4\) into the formula \(A=\frac{1}{2}\times b\times h\). We get \(A=\frac{1}{2}\times3\times4\).
First, calculate \(3\times4=12\). Then, \(\frac{1}{2}\times12 = 6\).
