Question

what is the area of the triangle? 0.4 in, 0.5 in, 0.2 in. square inches submit

Explanation:

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

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

Step2: Identify the base and height from the diagram.

From the diagram, the base of the right triangle is \( 0.2 \) inches and the height is \( 0.4 \) inches.

Step3: Substitute the values into the formula.

Substitute \( \text{base} = 0.2 \) and \( \text{height} = 0.4 \) into the formula:
\( A = \frac{1}{2} \times 0.2 \times 0.4 \)

Step4: Calculate the area.

First, multiply \( 0.2 \) and \( 0.4 \): \( 0.2 \times 0.4 = 0.08 \).
Then, multiply by \( \frac{1}{2} \): \( \frac{1}{2} \times 0.08 = 0.04 \).

Answer:

\( 0.04 \)
