    Area of Shaded Triangle

    Express the area of the shaded triangle in terms of "y".

    I have attached a picture of the problem. As you can see, I have already tried to solve the problem, but to no avail. I cannot figure it out at all. Any ideas?

    The answer is to be in terms of y.
    Every point ont your line is (4-2y,y)
    The width is 4-2y and the length is y.
    What is the area?
