Calculation of the Rectangle's Area

To find the area of a rectangle, we multiply the length of one side by the length of the other side. In this case, we have a rectangle with sides measuring 2 dm and 5 cm.

To ensure consistent units, we need to convert both measurements to the same unit. Since 1 dm is equal to 10 cm, we can convert 2 dm to cm by multiplying it by 10.

Therefore, the length of the rectangle is 20 cm (2 dm * 10 cm/dm) and the width is 5 cm.

To find the area, we multiply the length and width:

Area = length * width = 20 cm * 5 cm = 100 cm².

Therefore, the area of the rectangle is 100 square centimeters.
