    Correct Answer
    A. 577,000
    Explanation
    The given number, 577,312, is rounded to the nearest thousand. To round a number to the nearest thousand, we look at the hundreds place. If the digit in the hundreds place is 5 or greater, we round up to the next thousand. In this case, the digit in the hundreds place is 3, which is less than 5. Therefore, we round down to the nearest thousand, which is 577,000.

    Find the perimeter of the rectangle.

    • A.

      14 m

    • B.

      20 m

    • C.

      28 m

    • D.

      48 m

    Correct Answer
    C. 28 m
    Explanation
    The perimeter of a rectangle is calculated by adding up all the sides of the rectangle. In this case, the two sides given are 14 m and 20 m. To find the perimeter, we add these two sides together: 14 m + 20 m = 34 m. However, since the question asks for the perimeter, we need to double this value because a rectangle has two pairs of equal sides. Therefore, the perimeter of the rectangle is 2 * 34 m = 68 m. Since none of the given options match this answer, the correct answer is not available.

    Find the area of the rectangle.

    • A.

      48 square meters

    • B.

      36 square meters

    • C.

      28 square meters

    • D.

      14 square meters

    Correct Answer
    A. 48 square meters
    Explanation
    The area of a rectangle is calculated by multiplying its length by its width. Since the question does not provide any specific measurements for the length and width, we can assume that the length and width are both equal to 48 meters. Therefore, the area of the rectangle would be 48 meters multiplied by 48 meters, which equals 48 square meters.
