xin uses 20 yards of fencing to build the walls of a square chicken coop. What equation and solution represent x, the length, in yards, of each wall of the square coop?

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
