The length of the rectangle is one whole 4/20 meters, and the width is 3/20 meters less than the length.

The length of the rectangle is one whole 4/20 meters, and the width is 3/20 meters less than the length. find the perimeter of the rectangle.

1. To solve the problem, you need to know the width. From the condition of the problem, the length and how much width is less than it are known. Find what the width of the rectangle is.

1 4/20 – 3/20 = 1 1/20 meters.

2. Let’s calculate its perimeter.

(1 4/20 + 1 1/20) * 2 = 2 5/20 * 2 = 45/20 * 2 = 4 1/2 = 4.5 meters.

Answer: 4.5 meters.
