Answer:
80 cm
Step-by-step explanation:
1 metre = 100cm
8 metre = 8×100 = 800
total length of ribbon = 800cm
total pieces reema need = 12
length of each piece = 60cm
total ribbon reema needs = 12×60 = 720
total ribbon reema needs = 720cm
extra ribbon : total length - reema need
800cm - 720cm
= 80 cm
