Question

students are painting flags of many countries on walls at their school. the rectangular flag of eritrea will be 6 ft tall, as shown in the diagram. the length of the flag will be twice the height. the section labeled g will be painted green. what is the area of the wall that will be painted green? ft²

Explanation:

Step1: Identify the formula for the area of a triangle

The area of a triangle is given by \(A=\frac{1}{2}\times base\times height\).

Step2: Determine the base and height of the green - painted triangle

From the problem, the base of the triangle (labeled \(G\)) is \(12\) ft (the length of the flag) and the height is \(3\) ft.

Step3: Calculate the area

Substitute the values into the formula: \(A = \frac{1}{2}\times12\times3\).
First, calculate \(12\times3=36\). Then, \(\frac{1}{2}\times36 = 18\).

Answer:

\(18\)
