A new square puzzle

Take any square. Take any random point within the square. Draw straight lines from that point to the midpoints of every side of the square. You will get four quadrilaterals. Three of them have areas of 40 units, 60 units and 80 units. What is the size of the total square?

This is an interesting problem and requires a little visualization and some basic memory of geometry.
