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

From the right - triangle, the base $b = 5$ ft and the height $h=12$ ft.

Step3: Calculate the area

Substitute $b = 5$ and $h = 12$ into the formula: $A=\frac{1}{2}\times5\times12$.
$A=\frac{1}{2}\times60 = 30$ square feet.

Answer:

$30$ square feet
