The width of the rectangle is 8 dm, which is 1 m. 2 dm. less length. What is the perimeter of this rectangle.

First, we need to convert all values to one unit of measurement. There are 10 decimeters in one meter, which means:

1 m 2 dm = 10 + 2 = 12 dm the width of the rectangle is less than the length.

To find the perimeter of a rectangle, you need to know its length and width. Find the length of the rectangle – add 12 dm to the width:

8 + 12 = 20 dm rectangle length.

Now we can calculate the perimeter of the rectangle. Add its length and width and multiply by two:

2 (8 + 20) = 2 * 28 = 56 dm2

Answer: the perimeter of the rectangle is 56 dm2.
