Explanation:

Step1: Identify the shape of the green - painted area

The green - painted area is a triangle.

Step2: Recall the formula for the area of a triangle

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

Step3: Determine the base and height of the triangle

The base $b = 6$ ft and the height $h=12$ ft.

Step4: Calculate the area

$A=\frac{1}{2}\times6\times12 = 36$ square feet.

Answer:

$36$ square feet
