Answer:
3.38m
Step-by-step explanation:
the operation for this problem is subtraction
just subtract the needed meters of cloth to the cloth the subject has and there you go, but for confirmation that your answer is correct, add your answer to the cloth the subject has and if the result is the same as the needed one then you're correct :D
for example
6.5 - 3.12 = 3.38
now for confirmation
3.38 + 3.12 = 6.5
i hope this helps, pardon me for my grammatical errors. english might be my first language but i'm still learning further more about correct wording and grammars :]
