Answer: 80 cm or 160 cm
Step-by-step explanation: I'm not entirely sure what the 8cm is there for, but if BC is 8cm, then the entire length is 80, but if that's a midpoint, the entire length is 160. Hope this is helpful!
8/1 = 10/100
80/1= 100/100
Midpoint solution:
8= 1/2BC
16=BC
16/1= 10/100
160=100/100
