The area shown is enclosed between 4 lines. First, determine these lines.

On of them is the y-axis, x = 0. The other is a horizontal line y = 2.

The third line is represented by `x/5 + y/10 = 1` or 10x + 5y - 50 = 0. The fourth line is represented by the equation `x/-2 + y/6 = 1` or 6x - 2y + 12 = 0.

The given area is the solution of the inequalities: x > 0, y > 2, y < 3x + 6 and y < 10 - 2x
