Question: 593

4. The perimeter of a square with a side of length 4 is how much less than the perimeter of a rectangle with sides of length 4 and width 6 ?

  • A. 0
  • B. 2
  • C. 4
  • D. 6

Correct Answer: C

Explanation:

Take this question in bite-sized pieces. First, find the perimeter of a square with a side length of 4 by adding up all the sides: 4 + 4 + 4 + 4 = 16. Next, the perimeter of the rectangle with length 4 and width 6 is 4 + 4 + 6 + 6 = 20. The question asks for the difference between the two, so 20 - 16 = 4. The correct answer is (C).
