To read 2.20 dm on your constructed scale:

Break down the measurement.
The measurement 2.20 dm can be broken down into 2 dm and 0.20 dm.
Convert the decimal part to centimeters.
Since 1 dm = 10 cm, then 0.20 dm = $0.20 \times 10 \text{ cm} = 2 \text{ cm}$ .
So, you need to measure 2 dm and 2 cm.
Locate the decimeter mark.
On your scale, find the main division labeled '2' (this represents 2 dm). This is the starting point for your measurement.
Locate the centimeter mark.
From the '0' mark (which is the starting point for the centimeter subdivisions to the left), move to the left until you reach the mark labeled '2' in the centimeter section.
Measure the total length.
The total length of 2.20 dm is the distance from the '2' dm mark on the right to the '2' cm mark on the left side of the '0' point. You would use a divider or a ruler to transfer this length.
