Calculating Area and Perimeter

The video tutorial discusses Farmer Johnson's problem of enclosing a rectangular plot with an area of 144 square yards. It presents three plot options: 12x12, 24x6, and 18x8 yards, confirming each has the required area. The tutorial then calculates the perimeter for each plot to determine which requires the least fencing material, concluding that the 12x12 plot is optimal. The video encourages students to verify their answers with a teacher.
