Question

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

Explanation:

Step1: Recall area formula

The area formula for a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height.

Step2: Identify base and height

For the given right - triangle, the base $b = 18$ ft and the height $h=24$ ft.

Step3: Calculate the area

Substitute $b = 18$ and $h = 24$ into the formula: $A=\frac{1}{2}\times18\times24$. First, $\frac{1}{2}\times18 = 9$, then $9\times24=216$ square feet.

Answer:

$216$ ft²
