How many acres are in the N ½ of the NW ¼ of the SE ¼ and the SE ¼ of the SE ¼ of the SE ¼ of a section?

To calculate the number of acres in the specified parcels, first note that a section is 640 acres. The N ½ of the NW ¼ of the SE ¼ represents 1/2 of 1/4 of 1/4 of the section, which is (1/2) * (1/4) * (1/4) * 640 = 20 acres. The SE ¼ of the SE ¼ of the SE ¼ is (1/4) * (1/4) * (1/4) * 640 = 10 acres. Adding these together, the total is 20 acres + 10 acres = 30 acres.
