• math (distance problem) -

Draw a sketch and think it through, one statement at a time.
The first tells you that the total length is 20 cm.
The second tells you that D is 5 cm from the the right end (E).
The third tells you that B is 10 cm from each end (and in the middle). The fourth tells you where to put C
etc
