The length of the rectangular blanket is 18 dm, and the width is 2/9 of its length.

The length of the rectangular blanket is 18 dm, and the width is 2/9 of its length. How long should the braid be taken to sew this blanket?

1. From the problem statement we know that the plaid has the shape of a rectangle. Moreover, the length of this blanket is 18 dm.

2. Let’s calculate what the width of this blanket is equal to if we know that it is 2/9 of its length. This means that the length of the blanket must be multiplied by the part that is its width. Let’s calculate the product of the given values.

18 * 2/9 = 36/9 = 4 dm.

3. And now we find out how long it is necessary to take in order to sew this blanket. To do this, we need to add the lengths of all its sides.

18 + 18 + 4 + 4 = 44 dm.
