Question

what is the area of the triangle? 9 in. 4 in. square inches submit

Explanation:

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

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

Step2: Identify the base and height

In the given right triangle, the base is \( 4 \) inches and the height is \( 9 \) inches.

Step3: Substitute the values into the formula

Substitute \( \text{base} = 4 \) and \( \text{height}=9 \) into the formula: \( A=\frac{1}{2}\times4\times9 \).
First, calculate \( 4\times9 = 36 \), then \( \frac{1}{2}\times36 = 18 \).

Answer:

18
