A surveyor fixes a 200 -ft baseline between points A and B , where B is due east of A The bearing from A to a third point P is S 37 ° W and the bearing from B to P is S 62 ° W . Find the perimeter and area of the triangular plot of land formed by A , B , and P . Round the perimeter to the nearest foot and the area to the nearest 100 square feet.
