Iam measurng two line segments the first line is 30centi meter long the second line segment is 500milli meter how long are the two line segments together answer in cm

Answer    

Find out the how long are the two line segments together answer in cm .

To prove

As given

i am measurng two line segments the first line is 30centimeter long.

The second line segment is 500 millimeter .

As

1 millimeter = 0.1 centimeter

Now convert  500 millimeter into centimeter .

500 millimeter = 500 × 0.1 centimeter

                         = 50 centimeter

Thus second line segment be  50 centimeter long .

Total length of  two line segments = 30 + 50

                                                        = 80 cm

Therefore the 80 cm long are the two line segments together answer in cm .
