1. Let’s translate the value of the perimeter in centimeters:
40 dm = 400 cm.
2. According to the formula a = P / 2 – b, where P is the perimeter of a rectangle with length and width a and b, we find the width a:
a = 400/2 – 12 cm = 200 – 12 = 188 cm.
Answer: The width of the rectangle is 188 centimeters.
