The base of a triangle is 3m longer than the height. Find the base if the area of this triangle is 77m^2.

    Area = 1/2 base * Height

    Base = height - 3

    77 = 1/2 (height - 3)(height)

    Solve for height and put that value into the second equation. Check by putting both values into the second equation.
