If AB and CD are the same distance, BC is twice the distance of either of these two and DE is triple this length, we can calculate the total below:
x+2x+x+3x=7x
There are seven parts to the line. Three of these are DE which has length of 9cm. One part is equal to 3 cm so:
7 (3cm) = 21 cm

If AB and CD Are the Same Distance, BC Is
