For a point P in the plane, let$d_1\left(P\right)$and$d_2\left(P\right)$be the distances of the point P from the lines$x-y=0$and$x+y=0$respectively. The area of the region R consisting of all points P lying in the first quadrant of the plane and satisfying$2 \le d_1\left(P\right)+d_2\left(P\right) \le 4,$is ________
