The total length of two line segments is 80 cm
A line segment is just part of a line. It has two endpoints,
given that
the first line segment is 30cm
the second line segment is 500mm
now we need to convert it into cm from mm
To convert mm to cm, we need to multiply the length in mm by 0.1 cm since 1 mm is equal to 0.1 cm.
500 mm × 0.1 cm = 50cm
now we need to add two line segments
30 cm + 50 cm = 80 cm
The total length of two line segments is 80 cm
