Answer 1

Answer:

Answer for 32. The longest tape that can measure the given lengths is 35 cm

Step-by-step explanation:

So now,

7m = 7x100= 700 cm {1m=100cm}

3m+85cm=385 cm

12m+95cm=1295 cm

Now we can take the HCF of 700,385,1295 which is = 35

Therefore, the longest tape that can measure all the given lengths is 35cm long.
