find the area.\narea of a triangle\n$a = \\frac{bh}{2}$\n$a = ? \\text{ cm}^2$
Answer
Explanation:
Step1: Identify the base and height
The base $b$ is $9\text{ cm}$ and the height $h$ is $10\text{ cm}$.
Step2: Apply the triangle area formula
$$A = \frac{b \times h}{2}$$
Step3: Substitute the given values
$$A = \frac{9 \times 10}{2}$$
Step4: Calculate the final result
$$A = \frac{90}{2} = 45$$
Answer:
$45\text{ cm}^2$
