Calculating the Sum of Lengths of Given Segments

To find the length of the segment that is the sum of the given segments, we can add the lengths of the two segments together.

The given segments are: - 7 cm 5 mm - 2 cm 3 mm

Let's calculate the sum of these lengths.

Calculation

The sum of the given segments is: - 7 cm 5 mm + 2 cm 3 mm

To add these lengths, we can first convert the millimeters to centimeters and then perform the addition.

Converting millimeters to centimeters: - 5 mm = 0.5 cm - 3 mm = 0.3 cm

Now, we can add the lengths: - 7 cm 0.5 cm + 2 cm 0.3 cm = 9 cm 0.8 cm

Answer

The length of the segment that is the sum of the given segments is 9 cm 8 mm, which corresponds to option b) 9 cm 8 mm.
