Explanation:

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

The area \( A \) of a right triangle is given by \( A=\frac{1}{2}\times\text{base}\times\text{height} \). Here, the base is \( 0.5 \) yd and the height is \( 0.4 \) yd.

Step2: Substitute the values into the formula.

\( A = \frac{1}{2}\times0.5\times0.4 \)
First, calculate \( 0.5\times0.4 = 0.2 \). Then, \( \frac{1}{2}\times0.2 = 0.1 \).

Answer:

\( 0.1 \)
