Question

find the area. 12 in 18 in a = ? in²

Explanation:

Step1: Recall the area formula for a triangle

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

Step2: Identify the base and height

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

Step3: Substitute values into the formula

Substitute \(b = 18\) and \(h = 12\) into \(A=\frac{1}{2}\times b\times h\). So \(A=\frac{1}{2}\times18\times12\).
First, calculate \(18\times12 = 216\). Then, \(\frac{1}{2}\times216=108\).

Answer:

108
