# Construction Site

This image shows an overhead view of a construction site. In the illustration, you can see roads that form rectangles within a square.

On the upper-left side of the square is a road that has no intersections. The roads that form the “top” and “bottom” sides of the square have intersections that divide each road into three parts in the ratio 5:3:4. The lower-right road is divided into two parts in the ratio 6:6. These ratios are shown in the diagram.

You cannot determine the actual length of each side of the square based on the information provided; however, assume that the length is 12 units.

- Without calculating, estimate the percent of the total area of the square that is represented by Rectangle A.
