title: How to change a rectangle's area based on it's coordinates?
body: <p>I'm developing an Android app. I have a polygon/rectangle with it's 4 bounds/coordinates on a Google Map. I have a variable named <code>areaDifference</code> which is set to an arbitrary value. I need to take the value of this variable and change the size of the rectangle. For instance, if <code>areaDifference</code> is set to 2, I need to make the rectangle twice as big. How do i change the size? I only have the 4 coordinates and the area variable.</p>
