The width of the rectangle is 3 dm, and the length is 52 cm, find its area and perimeter.

Since 1 dm = 10 cm, the width of the rectangle is 3 dm = 3 * 10 cm = 30 cm. The perimeter of the rectangle is equal to the sum of all its sides. Since the opposite sides of the rectangle are equal, then P = 2 * a + 2 * b. Substituting the known values of the sides, we find the value of the perimeter: P = 2 * 30 cm + 2 * 52 cm = 60 cm + 104 cm = 164 cm.The area of the rectangle is equal to the product of length and width: S = a * b, S = 30 cm * 52 cm = 1560 cm square.
Answer: the perimeter value is 164 cm, and the area value is 1560 cm2.
