The correct answer is 14 square feet.
To find the total area of the arrow, we need to find the area of the rectangle and the area of the triangle, and then add them together.
Area of rectangle = length x width
Area of rectangle = 4 x 2 = 8 square feet
Area of triangle = 0.5 x base x height
Area of triangle = 0.5 x 4 x 5 = 10 square feet
Total area = area of rectangle + area of triangle
Total area = 8 + 10 = 18 square feet
The total area that will be painted is 18 square feet, not 14 square feet. 14 square feet is not the correct answer.
