Question

find the area.
12 ft
18 ft
a = ? ft²

Explanation:

Step1: Recall the formula for the area of a triangle

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

Step2: Identify the base and height

Here, the base \(b = 18\) ft and the height \(h=12\) ft.

Step3: Substitute the values into the formula

\(A=\frac{1}{2}\times18\times12\). First, calculate \(18\times12 = 216\). Then, \(\frac{1}{2}\times216=108\).

Answer:

\(108\)
