When measuring a certain segment AB, a segment PQ with a length of 1 m 1 cm 1 mm was taken as a unit.

When measuring a certain segment AB, a segment PQ with a length of 1 m 1 cm 1 mm was taken as a unit. It turned out that the length of a segment AB in such units is 20. What is the length of a segment AB in centimeters?

First, we translate the unit segment PQ 1 m 1 cm 1 mm into a decimal numerical value and express it in centimeters, we get: PQ = 101.1 cm.We write down the proportion 101.1 belongs to one, and 20 units belongs to the segment AB, then as a result solutions we get:

AB = 20 * PQ = 20 * 101.1 = 2022 cm.

Answer: The segment AB is equal to two thousand twenty two centimeters.
