Step-by-step explanation:

The area needed for painting is a triangle with base = 6 and height = 4

Area of a Triangle is given by:

Where b is the base

and

h is the height

So area needed for painting is:

Given,

10 sq. ft. requires 6.79 dollars, we need to find how much dollars would be need to paint 12 sq. ft.

We can write a ratio and solve for the amount Aubrey would need (let amount be "x"). We write ratio, cross multiply, and solve. Shown below:

Aubrey would need $8.15 to paint the sail
