Question

find the area of the triangle.

a=

in²

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

From the figure, the base \(b = 9\) in and the height \(h=12\) in.

Step3: Substitute the values into the formula

\(A=\frac{1}{2}\times9\times12\). First, calculate \(9\times12 = 108\). Then, \(\frac{1}{2}\times108=54\).

Answer:

\(54\)
