If you label the 4 points A,B,C,D then it is easy to find the lengths of the 4 sides. Now, the length of AC is 551.
Now you have two triangles, and you know all the sides, so you can use Heron's formula to get the areas.
Draw the picture and find the area of the parcel of land. Circle your to partial areas and your total area. You start herman a corn and walk 300 yards due north. Then, you turn N 63 degrees E and walk 260 yards. Then, you turn S 55 degrees E and walk 240 yards. Then, you walk back to the little acorns.
