Question

the area of a triangle with base b and height h is \frac{1}{2}bh. jon works for an advertising agency, where he designed a billboard shaped like a tortilla chip. the tortilla chip billboard is 15 feet high and 12 feet wide at its base. what is the area of the tortilla chip billboard? write your answer as a whole number or decimal. square feet

Explanation:

Step1: Substitute the values into the formula

Given the formula for the area of a triangle \(A=\frac{1}{2}bh\), where \(b = 12\) (base) and \(h=15\) (height).

Step2: Calculate the product of \(b\) and \(h\)

First, find \(bh\): \(12\times15 = 180\).

Step3: Multiply by \(\frac{1}{2}\)

Then, \(A=\frac{1}{2}\times180\).

Answer:

\(90\)
