Let’s find the width of the rectangle from the condition: b = a / 5 = 1/5 = 0.2 dm.
As you know, the perimeter of a rectangle is calculated by the formula: P = (a + b) * 2, where a is the length of the rectangle, b is the width of the rectangle.
Substitute all known values in the formula: P = (1 + 0.2) * 2 = 2 + 0.4 = 2.4 dm.
Answer: The perimeter of the rectangle is 2.4 dm.
