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 shape of the green - painted area

The green - painted area is a triangle.

Step2: Determine the base and height of the triangle

The height of the triangle is 12 ft and the base is 6 ft.

Step3: Use the triangle - area formula

The area formula for a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height. Substitute $b = 6$ and $h=12$ into the formula: $A=\frac{1}{2}\times6\times12$.

Step4: Calculate the area

$A = 36$ square feet.

Answer:

36
