The area of a rectangle is 560 dm square and a width of 8 cm find its length and perimeter.

560 square dm we translate into square cm-560 * 100 = 56000 square cm.
The area of the rectangle is equal to the product of the length and the width. To find one of the sides of a rectangle, you need to divide the area of the rectangle by the known side. The length of the rectangle is 56000/8 = 7000 cm Let’s find the perimeter P = 2 * 8 + 2 * 7000 = 16 + 14000 = 14016 cm.
Answer: 14016
