Question

find the area of the triangle below. be sure to include the correct unit in your answer.

Explanation:

Step1: Recall triangle area formula

The area of a triangle is $\frac{1}{2} \times \text{base} \times \text{height}$.

Step2: Identify base and height

Base $= 11\ \text{cm}$, Height $= 9\ \text{cm}$

Step3: Substitute values into formula

$\text{Area} = \frac{1}{2} \times 11 \times 9$

Step4: Calculate the result

$\frac{1}{2} \times 99 = 49.5$

Step5: Choose correct unit

Area uses square units, so $\text{cm}^2$.

Answer:

$49.5\ \text{cm}^2$
