Answer:
65 cm
Step-by-step explanation:
Remember that
[tex]1\ m=100\ cm[/tex]
step 1
Convert 2.5 m to cm
[tex]2.5\ m=2.5(100)=250\ cm[/tex]
step 2
To find out how much of the initial long pipe is left, subtract the lengths of 60 cm, 35 cm and 90 cm from the initial long pipe
[tex]250-(60+35+90)=250-185=65\ cm[/tex]
