According to the condition of the problem, the length of a given rectangular sheet of paper is 6 dm, and the width of this sheet is 3 dm.
The area of any rectangle is equal to the product of the length and width of this rectangle, therefore, the area S of a given rectangular sheet of paper is:
S = 6 * 3 = 18 dm².
The perimeter of any rectangle is equal to twice the sum of the length and width of this rectangle, therefore, the perimeter P of this rectangular sheet of paper is:
P = 2 * (6 + 3) = 2 * 9 = 18 dm.
Answer: the area of this sheet of paper is 18 dm², the perimeter of this sheet of paper is 18 dm².
