To find the area of the triangle, you would use the formula for the area of a triangle which is 1/2 * base * height.
In this case, the base of the triangle is 22 feet and the distance from the vertex to the base (height) is 6 feet.
Therefore, the equation to find the area of this triangle would be:
Area = 1/2 * 22 feet * 6 feet
Area = 66 square feet
