    Given that the base of the triangle is x m, the height is 3m less than twice it's base then the height will be represented by the equation:

    (2x-3) m

    Thus the area will be:

    Area=1/2bh

    Area=1/2x (2x-3) = 17.5

    x^2-1.5x=17.5

    Writing the above equation is quadratic form of ax^2+bx+c=0 we get:

    x^2-1.5x-17.5=0
