solving a real - world problem
the sign for a new restaurant will be a triangle with a base of 8 feet and a height of 3 feet. the painter needs to know if
he has enough paint to cover the sign. find the area of the sign in square feet.
the area of the sign is
\\( \square \\) square feet.

Explanation:

Step1: Recall the formula for the area of a triangle

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

Step2: Substitute the given values into the formula

Given \(b = 8\) feet and \(h=3\) feet. Substitute these values into the formula: \(A=\frac{1}{2}\times8\times3\).
First, calculate \(8\times3 = 24\). Then, \(\frac{1}{2}\times24=12\).

Answer:
