Question

find the area. a = ? ft²

Explanation:

Step1: Recall area formula for triangle

The formula for the area of a triangle is $A=\frac{1}{2}\times base\times height$.

Step2: Identify base and height

From the figure, the base of the triangle is $b = 24$ ft and the height is $h=16$ ft.

Step3: Calculate the area

Substitute the values into the formula: $A=\frac{1}{2}\times24\times16$. First, $\frac{1}{2}\times24 = 12$, then $12\times16=192$ square - feet.

Answer:

$192$
