Answer: The leftover piece will be 21.95 cm long.
Step-by-step explanation:
Hi, to answer this we have to subtract the sum of the total length of the pieces she needs to cut (25.5 cm, 15.3 cm, and 9.25 cm) to the strip's length (72)
Mathematically speaking:
72- (25.5+15.3+9.25) = 72- 50.05= 21.95cm
The leftover piece will be 21.95 cm long.
