The answer is 11 :) hope this helps
The answer is 2/3 I think
Step-by-step explanation:
i do believe the answer is 18
If the width is 6.5 then double that to work out the two widths which would be 13. Take that from the perimeter so you're left with 21. Half 21 to work out one length which is 10.5. Length = 10.5

I hope this this is what you need ..
