Question

find the area of the triangle below. be sure to include the correct unit in your answer.

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 \(b = 15\) ft and the height \(h=15\) ft.

Step3: Substitute the values into the formula

Substitute \(b = 15\) and \(h = 15\) into \(A=\frac{1}{2}\times b\times h\). So, \(A=\frac{1}{2}\times15\times15\).
First, calculate \(15\times15 = 225\). Then, \(A=\frac{1}{2}\times225\).
\(A = 112.5\)

Answer:

\(112.5\) square feet
