Sandy said that if you know the area for any square, then you can find the side by dividing by 4 . Joe said that's not true, he couldn't support his argument. Sandy said, yes it is. If the area of the square is 16 , then the side is 4 . Who is correct Joe, support his argument. Jose is correct. He could have argued that \( 16 / 4 \) is not 4 . Joe is correct. He could have given a counterexample. For example a square with and area of 25 would have a sid. Sandy is correct. Joe is correct. He could have argued that the formula for perimeter is 4 s for the square. Question 4 Janice said that perimeter is always a bigger number than area. Is Janice correct? If not, give a counterexample to tha statement. Janice is wrong. A square with sides of 2 . Janice is correct. Janice is wrong. A rhombus with diagonals 6 and 8 . Janice is wrong. A right triangle with sides \( 3,4,5 \). Chatw J.

Answer

Joe is correct. Sandy's claim that you can find the side of a square by dividing the area by 4 is incorrect. The correct method is to take the square root of the area. Additionally, Janice is wrong because the perimeter of a square is not always larger than its area; for example, a square with sides of 0.5 has a perimeter of 2 and an area of 0.25, where the perimeter is larger.

Beyond the Answer

Joe is correct about Sandy's misunderstanding. To find the side length of a square, you actually need to take the square root of the area. So, for an area of 16, it's \( \sqrt{16} = 4 \). If Sandy had said "divide by 4," that wouldn't work for other areas like 25, where dividing by 4 gives you 6.25, which is incorrect. As for Janice, she is wrong. A counterexample is a square with a side length of 1. The area is \( 1^2 = 1 \) while the perimeter is \( 4(1) = 4 \). In this case, the perimeter (4) is greater than the area (1), proving that Janice's statement isn't always true!
