Question

write an equation for the area, a, of the triangle shown. 12 ft 20 ft

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 given triangle, the base \(b = 20\) ft and the height \(h=12\) ft.

Step3: Substitute the values into the formula

Substituting \(b = 20\) and \(h = 12\) into \(A=\frac{1}{2}\times base\times height\), we get \(A=\frac{1}{2}\times12\times20\).

Answer:

\(A=\frac{1}{2}\times12\times20\)
