If a rectangular field measures 20 feet by 10 feet, what is its perimeter?

  1. 40 feet

  2. 60 feet

  3. 30 feet

  4. 50 feet

The correct answer is: 40 feet

To calculate the perimeter of a rectangular field, you can use the formula: Perimeter = 2 × (length + width) In this case, the length is 20 feet and the width is 10 feet. Plugging those values into the formula gives: Perimeter = 2 × (20 feet + 10 feet) Perimeter = 2 × 30 feet Perimeter = 60 feet. Thus, the correct answer for the perimeter of the rectangular field is 60 feet. In evaluating the other options, 40 feet is half the actual value calculated, while 30 feet and 50 feet do not correspond to the correct mathematical computation for the perimeter of a rectangle with the given dimensions.
